Overview

Individual or compiled

Plugins can be included individually (using Bootstrap's individual *.js files), or all at once (using bootstrap.js or the minified bootstrap.min.js). Also include visma-additional.js file for some custom changes added by Visma.

Using the compiled JavaScript

Both bootstrap.js and bootstrap.min.js contain all plugins in a single file. Include only one.

Plugin dependencies

Some plugins and CSS components depend on other plugins. Is recommended to include bootstrap.js or bootstrap.min.js and visma-additional.js. Also note that all plugins depend on jQuery (this means jQuery must be included before the plugin files). Consult our bower.json to see which versions of jQuery are supported.

Data attributes

You can use all Bootstrap plugins purely through the markup API without writing a single line of JavaScript. This is Bootstrap's first-class API and should be your first consideration when using a plugin.

That said, in some situations it may be desirable to turn this functionality off. Therefore, we also provide the ability to disable the data attribute API by unbinding all events on the document namespaced with data-api. This looks like this:

$(document).off('.data-api')

Alternatively, to target a specific plugin, just include the plugin's name as a namespace along with the data-api namespace like this:

$(document).off('.alert.data-api')

Only one plugin per element via data attributes

Don't use data attributes from multiple plugins on the same element. For example, a button cannot both have a tooltip and toggle a modal. To accomplish this, use a wrapping element.

Programmatic API

We also believe you should be able to use all Bootstrap plugins purely through the JavaScript API. All public APIs are single, chainable methods, and return the collection acted upon.

$('.btn.danger').button('toggle').addClass('fat')

All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a plugin with default behavior):

$('#myModal').modal()                      // initialized with defaults
$('#myModal').modal({ keyboard: false })   // initialized with no keyboard
$('#myModal').modal('show')                // initializes and invokes show immediately

Each plugin also exposes its raw constructor on a Constructor property: $.fn.popover.Constructor. If you'd like to get a particular plugin instance, retrieve it directly from an element: $('[rel="popover"]').data('popover').

Default settings

You can change the default settings for a plugin by modifying the plugin's Constructor.DEFAULTS object:

$.fn.modal.Constructor.DEFAULTS.keyboard = false // changes default for the modal plugin's `keyboard` option to false

No conflict

Sometimes it is necessary to use Bootstrap plugins with other UI frameworks. In these circumstances, namespace collisions can occasionally occur. If this happens, you may call .noConflict on the plugin you wish to revert the value of.

var bootstrapButton = $.fn.button.noConflict() // return $.fn.button to previously assigned value
$.fn.bootstrapBtn = bootstrapButton            // give $().bootstrapBtn the Bootstrap functionality

Events

Bootstrap provides custom events for most plugins' unique actions. Generally, these come in an infinitive and past participle form - where the infinitive (ex. show) is triggered at the start of an event, and its past participle form (ex. shown) is triggered on the completion of an action.

As of 3.0.0, all Bootstrap events are namespaced.

All infinitive events provide preventDefault functionality. This provides the ability to stop the execution of an action before it starts.

$('#myModal').on('show.bs.modal', function (e) {
  if (!data) return e.preventDefault() // stops modal from being shown
})

Version numbers

The version of each of Bootstrap's jQuery plugins can be accessed via the VERSION property of the plugin's constructor. For example, for the tooltip plugin:

$.fn.tooltip.Constructor.VERSION // => "3.3.6"

No special fallbacks when JavaScript is disabled

Bootstrap's plugins don't fall back particularly gracefully when JavaScript is disabled. If you care about the user experience in this case, use <noscript> to explain the situation (and how to re-enable JavaScript) to your users, and/or add your own custom fallbacks.

Third-party libraries

Bootstrap does not officially support third-party JavaScript libraries like Prototype or jQuery UI. Despite .noConflict and namespaced events, there may be compatibility problems that you need to fix on your own.

Transitions

About transitions

For simple transition effects, include transition.js once alongside the other JS files. If you're using the compiled (or minified) bootstrap.js, there is no need to include this—it's already there.

What's inside

Transition.js is a basic helper for transitionEnd events as well as a CSS transition emulator. It's used by the other plugins to check for CSS transition support and to catch hanging transitions.

Disabling transitions

Transitions can be globally disabled using the following JavaScript snippet, which must come after bootstrap.js or bootstrap.min.js (as the case may be) has loaded:

$.support.transition = false

Vertical menu

Indicate the current page's location within a vertical navigation.

This navigation is responsive and becomes horizontal as the available viewport width decreases.

Modals

Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.

Overlapping modals not supported

Be sure not to open a modal while another is still visible. Showing more than one modal at a time requires custom code.

Always try to place a modal's HTML code in a top-level position in your document to avoid other components affecting the modal's appearance and/or functionality.

Due to how HTML5 defines its semantics, the autofocus HTML attribute has no effect in Bootstrap modals. To achieve the same effect, use some custom JavaScript:

$('#myModal').on('shown.bs.modal', function () {
  $('#myInput').focus()
})

Examples

Static example

A rendered modal with header, body, and set of actions in the footer.

Live demo

Toggle a modal via JavaScript by clicking the button below. It will slide down and fade in from the top of the page.

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-primary">Save changes</button>
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>

Make modals accessible

Be sure to add role="dialog" to .modal, aria-labelledby="myModalLabel" attribute to reference the modal title, and aria-hidden="true" to tell assistive technologies to skip the modal's DOM elements.

Additionally, you may give a description of your modal dialog with aria-describedby on .modal.

Embedding YouTube videos

Embedding YouTube videos in modals requires additional JavaScript not in Bootstrap to automatically stop playback and more. See this helpful Stack Overflow post for more information.

Optional sizes

Modals have two optional sizes, available via modifier classes to be placed on a .modal-dialog.

<!-- Large modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bs-example-modal-lg">Large modal</button>

<div class="modal fade bs-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-lg">
    <div class="modal-content">
      ...
    </div>
  </div>
</div>

<!-- Small modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bs-example-modal-sm">Small modal</button>

<div class="modal fade bs-example-modal-sm" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-sm">
    <div class="modal-content">
      ...
    </div>
  </div>
</div>

Remove animation

For modals that simply appear rather than fade in to view, remove the .fade class from your modal markup.

<div class="modal" tabindex="-1" role="dialog" aria-labelledby="" aria-hidden="true">
  ...
</div>

Using the grid system

To take advantage of the Bootstrap grid system within a modal, just nest .container-fluid within the .modal-body and then use the normal grid system classes within this container.

<div class="modal fade" role="dialog" aria-labelledby="gridSystemModalLabel" aria-hidden="true">
    <div class="modal-dialog">
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
          <h4 class="modal-title" id="gridSystemModalLabel">Modal title</h4>
        </div>
        <div class="modal-body">
          <div class="container-fluid">
            <div class="row">

            <div class="row">

              <div class="col-md-2 col-md-offset-4">.col-md-2 .col-md-offset-4</div>
            </div>
            <div class="row">
              <div class="col-md-6 col-md-offset-3">.col-md-6 .col-md-offset-3</div>
            </div>
            <div class="row">
              <div class="col-sm-9">

        </div>
      </div><!-- /.modal-content -->

Have a bunch of buttons that all trigger the same modal, just with slightly different contents? Use event.relatedTarget and HTML data-* attributes (possibly via jQuery) to vary the contents of the modal depending on which button was clicked. See the Modal Events docs for details on relatedTarget,

        <button type="button" class="btn btn-primary">Send message</button>
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>

  </div>
</div>
$('#exampleModal').on('show.bs.modal', function (event) {
  var button = $(event.relatedTarget) // Button that triggered the modal
  var recipient = button.data('whatever') // Extract info from data-* attributes
  // If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
  // Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
  var modal = $(this)
  modal.find('.modal-title').text('New message to ' + recipient)
  modal.find('.modal-body input').val(recipient)
})

Usage

The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also adds .modal-open to the <body> to override default scrolling behavior and generates a .modal-backdrop to provide a click area for dismissing shown modals when clicking outside the modal.

Via data attributes

Activate a modal without writing JavaScript. Set data-toggle="modal" on a controller element, like a button, along with a data-target="#foo" or href="#foo" to target a specific modal to toggle.

<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>

Via JavaScript

Call a modal with id myModal with a single line of JavaScript:

$('#myModal').modal(options)

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-backdrop="".

Name type default description
backdrop boolean or the string 'static' true Includes a modal-backdrop element. Alternatively, specify static for a backdrop which doesn't close the modal on click.
keyboard boolean true Closes the modal when escape key is pressed
show boolean true Shows the modal when initialized.
remote path false

This option is deprecated since v3.3.0 and will be removed in v4. We recommend instead using client-side templating or a data binding framework, or calling jQuery.load yourself.

If a remote URL is provided, content will be loaded one time via jQuery's load method and injected into the .modal-content div. If you're using the data-api, you may alternatively use the href attribute to specify the remote source. An example of this is shown below:

<a data-toggle="modal" href="remote.html" data-target="#modal">Click me</a>

Methods

.modal(options)

Activates your content as a modal. Accepts an optional options object.

$('#myModal').modal({
  keyboard: false
})

.modal('toggle')

Manually toggles a modal. Returns to the caller before the modal has actually been shown or hidden (i.e. before the shown.bs.modal or hidden.bs.modal event occurs).

$('#myModal').modal('toggle')

.modal('show')

Manually opens a modal. Returns to the caller before the modal has actually been shown (i.e. before the shown.bs.modal event occurs).

$('#myModal').modal('show')

.modal('hide')

Manually hides a modal. Returns to the caller before the modal has actually been hidden (i.e. before the hidden.bs.modal event occurs).

$('#myModal').modal('hide')

.modal('handleUpdate')

Readjusts the modal's positioning to counter a scrollbar in case one should appear, which would make the modal jump to the left.

Only needed when the height of the modal changes while it is open.

$('#myModal').modal('handleUpdate')

Events

Bootstrap's modal class exposes a few events for hooking into modal functionality.

All modal events are fired at the modal itself (i.e. at the <div class="modal">).

Event Type Description
show.bs.modal This event fires immediately when the show instance method is called. If caused by a click, the clicked element is available as the relatedTarget property of the event.
shown.bs.modal This event is fired when the modal has been made visible to the user (will wait for CSS transitions to complete). If caused by a click, the clicked element is available as the relatedTarget property of the event.
hide.bs.modal This event is fired immediately when the hide instance method has been called.
hidden.bs.modal This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).
loaded.bs.modal This event is fired when the modal has loaded content using the remote option.
$('#myModal').on('hidden.bs.modal', function (e) {
  // do something...
})

Dropdowns

Add dropdown menus to nearly anything with this simple plugin, including the navbar, tabs, and pills.

Within a navbar

Via data attributes or JavaScript, the dropdown plugin toggles hidden content (dropdown menus) by toggling the .open class on the parent list item.

On mobile devices, opening a dropdown adds a .dropdown-backdrop as a tap area for closing dropdown menus when tapping outside the menu, a requirement for proper iOS support. This means that switching from an open dropdown menu to a different dropdown menu requires an extra tap on mobile.

Note: The data-toggle="dropdown" attribute is relied on for closing dropdown menus at an application level, so it's a good idea to always use it.

Via data attributes

Add data-toggle="dropdown" to a link or button to toggle a dropdown.

<div class="dropdown">
  <button id="dLabel" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
    Dropdown trigger
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
    ...
  </ul>
</div>

To keep URLs intact with link buttons, use the data-target attribute instead of href="#".

<div class="dropdown">
  <a id="dLabel" data-target="#" href="http://example.com" data-toggle="dropdown" aria-haspopup="true" role="button" aria-expanded="false">
    Dropdown trigger
    <span class="caret"></span>
  </a>

  <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
    ...
  </ul>
</div>

Via JavaScript

Call the dropdowns via JavaScript:

$('.dropdown-toggle').dropdown()

data-toggle="dropdown" still required

Regardless of whether you call your dropdown via JavaScript or instead use the data-api, data-toggle="dropdown" is always required to be present on the dropdown's trigger element.

None

$().dropdown('toggle')

Toggles the dropdown menu of a given navbar or tabbed navigation.

All dropdown events are fired at the .dropdown-menu's parent element.

All dropdown events have a relatedTarget property, whose value is the toggling anchor element.

Event Type Description
show.bs.dropdown This event fires immediately when the show instance method is called.
shown.bs.dropdown This event is fired when the dropdown has been made visible to the user (will wait for CSS transitions, to complete).
hide.bs.dropdown This event is fired immediately when the hide instance method has been called.
hidden.bs.dropdown This event is fired when the dropdown has finished being hidden from the user (will wait for CSS transitions, to complete).
$('#myDropdown').on('show.bs.dropdown', function () {
  // do something…
})

ScrollSpy scrollspy.js

Example in navbar

The ScrollSpy plugin is for automatically updating nav targets based on scroll position. Scroll the area below the navbar and watch the active class change. The dropdown sub items will be highlighted as well.

Usage

Requires Bootstrap nav

Scrollspy currently requires the use of a Bootstrap nav component for proper highlighting of active links.

Resolvable ID targets required

Navbar links must have resolvable id targets. For example, a <a href="#home">home</a> must correspond to something in the DOM like <div id="home"></div>.

Non-:visible target elements ignored

Target elements that are not :visible according to jQuery will be ignored and their corresponding nav items will never be highlighted.

Requires relative positioning

No matter the implementation method, scrollspy requires the use of position: relative; on the element you're spying on. In most cases this is the <body>.

Via data attributes

To easily add scrollspy behavior to your topbar navigation, add data-spy="scroll" to the element you want to spy on (most typically this would be the <body>). Then add the data-target attribute with the ID or class of the parent element of any Bootstrap .nav component.

body {
  position: relative;
}
<body data-spy="scroll" data-target="#navbar-example">
  ...
  <div id="navbar-example">
    <ul class="nav nav-tabs" role="tablist">
      ...
    </ul>
  </div>
  ...
</body>

Via JavaScript

After adding position: relative; in your CSS, call the scrollspy via JavaScript:

$('body').scrollspy({ target: '#navbar-example' })

Methods

.scrollspy('refresh')

When using scrollspy in conjunction with adding or removing of elements from the DOM, you'll need to call the refresh method like so:

$('[data-spy="scroll"]').each(function () {
  var $spy = $(this).scrollspy('refresh')
})

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-offset="".

Name type default description
offset number 10 Pixels to offset from top when calculating position of scroll.

Events

Event Type Description
activate.bs.scrollspy This event fires whenever a new item becomes activated by the scrollspy.
$('#myScrollspy').on('activate.bs.scrollspy', function () {
  // do something…
})

Togglable tabs

Example tabs

Add quick, dynamic tab functionality to transition through panes of local content, even via dropdown menus.

Extends tabbed navigation

This plugin extends the tabbed navigation component to add tabbable areas.

Usage

Enable tabbable tabs via JavaScript (each tab needs to be activated individually):

$('#myTab a').click(function (e) {
  e.preventDefault()
  $(this).tab('show')
})

You can activate individual tabs in several ways:

$('#myTab a[href="#profile"]').tab('show') // Select tab by name
$('#myTab a:first').tab('show') // Select first tab
$('#myTab a:last').tab('show') // Select last tab
$('#myTab li:eq(2) a').tab('show') // Select third tab (0-indexed)

Markup

You can activate a tab or pill navigation without writing any JavaScript by simply specifying data-toggle="tab" or data-toggle="pill" on an element. Adding the nav and nav-tabs classes to the tab ul will apply the Bootstrap tab styling, while adding the nav and nav-pills classes will apply pill styling.

<div role="tabpanel">

  <!-- Nav tabs -->
  <ul class="nav nav-tabs" role="tablist">
    <li role="presentation" class="active"><a href="#home" aria-controls="home" role="tab" data-toggle="tab">Home</a></li>
    <li role="presentation"><a href="#profile" aria-controls="profile" role="tab" data-toggle="tab">Profile</a></li>
    <li role="presentation"><a href="#messages" aria-controls="messages" role="tab" data-toggle="tab">Messages</a></li>
    <li role="presentation"><a href="#settings" aria-controls="settings" role="tab" data-toggle="tab">Settings</a></li>
  </ul>

  <!-- Tab panes -->
  <div class="tab-content">
    <div role="tabpanel" class="tab-pane active" id="home">...</div>
    <div role="tabpanel" class="tab-pane" id="profile">...</div>
    <div role="tabpanel" class="tab-pane" id="messages">...</div>
    <div role="tabpanel" class="tab-pane" id="settings">...</div>
  </div>

</div>

Fade effect

To make tabs fade in, add .fade to each .tab-pane. The first tab pane must also have .in to properly fade in initial content.

<div class="tab-content">
  <div role="tabpanel" class="tab-pane fade in active" id="home">...</div>
  <div role="tabpanel" class="tab-pane fade" id="profile">...</div>
  <div role="tabpanel" class="tab-pane fade" id="messages">...</div>
  <div role="tabpanel" class="tab-pane fade" id="settings">...</div>
</div>

Methods

$().tab

Activates a tab element and content container. Tab should have either a data-target or an href targeting a container node in the DOM.

<ul class="nav nav-tabs" role="tablist" id="myTab">
  <li role="presentation" class="active"><a href="#home" aria-controls="home" role="tab" data-toggle="tab">Home</a></li>
  <li role="presentation"><a href="#profile" aria-controls="profile" role="tab" data-toggle="tab">Profile</a></li>
  <li role="presentation"><a href="#messages" aria-controls="messages" role="tab" data-toggle="tab">Messages</a></li>
  <li role="presentation"><a href="#settings" aria-controls="settings" role="tab" data-toggle="tab">Settings</a></li>
</ul>

<div class="tab-content">
  <div role="tabpanel" class="tab-pane active" id="home">...</div>
  <div role="tabpanel" class="tab-pane" id="profile">...</div>
  <div role="tabpanel" class="tab-pane" id="messages">...</div>
  <div role="tabpanel" class="tab-pane" id="settings">...</div>
</div>

<script>
  $(function () {
    $('#myTab a:last').tab('show')
  })
</script>

Events

When showing a new tab, the events fire in the following order:

  1. hide.bs.tab (on the current active tab)
  2. show.bs.tab (on the to-be-shown tab)
  3. hidden.bs.tab (on the previous active tab, the same one as for the hide.bs.tab event)
  4. shown.bs.tab (on the newly-active just-shown tab, the same one as for the show.bs.tab event)

If no tab was already active, then the hide.bs.tab and hidden.bs.tab events will not be fired.

Event Type Description
show.bs.tab This event fires on tab show, but before the new tab has been shown. Use event.target and event.relatedTarget to target the active tab and the previous active tab (if available) respectively.
shown.bs.tab This event fires on tab show after a tab has been shown. Use event.target and event.relatedTarget to target the active tab and the previous active tab (if available) respectively.
hide.bs.tab This event fires when a new tab is to be shown (and thus the previous active tab is to be hidden). Use event.target and event.relatedTarget to target the current active tab and the new soon-to-be-active tab, respectively.
hidden.bs.tab This event fires after a new tab is shown (and thus the previous active tab is hidden). Use event.target and event.relatedTarget to target the previous active tab and the new active tab, respectively.
$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
  e.target // newly activated tab
  e.relatedTarget // previous active tab
})

Tooltips

Inspired by the excellent jQuery.tipsy plugin written by Jason Frame; Tooltips are an updated version, which don't rely on images, use CSS3 for animations, and data-attributes for local title storage.

Tooltips with zero-length titles are never displayed.

Examples

Hover over the links below to see tooltips:

Tight pants next level keffiyeh you probably haven't heard of them. Photo booth beard raw denim letterpress vegan messenger bag stumptown. Farm-to-table seitan, mcsweeney's fixie sustainable quinoa 8-bit american apparel have a terry richardson vinyl chambray. Beard stumptown, cardigans banh mi lomo thundercats.

Static tooltip

Four options are available: top, right, bottom, and left aligned.


Four directions

<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="left" title="Tooltip on left">Tooltip on left</button>

<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="top" title="Tooltip on top">Tooltip on top</button>

<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="bottom" title="Tooltip on bottom">Tooltip on bottom</button>

<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="right" title="Tooltip on right">Tooltip on right</button>

Validation state

Static tooltip

Here is the way an error tooltip should look like:


Four directions

Just add tooltip-error-trig class on the element that triggers the tooltip. Check the example and the code below.

<form class="form-horizontal">
  <div class="form-group has-error">
    <label for="tooltip1" class="col-sm-2 control-label">Tooltip on left</label>
    <div class="col-sm-10">
      <input type="text" class="form-control tooltip-error-trig" id="tooltip1" placeholder="Tooltip on left" data-toggle="tooltip" data-placement="left">
    </div>
  </div>
  
  <div class="form-group has-error">
    <label for="tooltip1" class="col-sm-2 control-label">Tooltip on top</label>
    <div class="col-sm-10">
      <input type="text" class="form-control tooltip-error-trig" id="tooltip1" placeholder="Tooltip on top" data-toggle="tooltip" data-placement="top">
    </div>
  </div>

  <div class="form-group has-error">
    <label for="tooltip1" class="col-sm-2 control-label">Tooltip on bottom</label>
    <div class="col-sm-10">
      <input type="text" class="form-control tooltip-error-trig" id="tooltip1" placeholder="Tooltip on bottom" data-toggle="tooltip" data-placement="bottom">
    </div>
  </div>

  <div class="form-group has-error">
    <label for="tooltip1" class="col-sm-2 control-label">Tooltip on right</label>
    <div class="col-sm-10">
      <input type="text" class="form-control tooltip-error-trig" id="tooltip1" placeholder="Tooltip on right" data-toggle="tooltip" data-placement="right">
    </div>
  </div>
</form>

Opt-in functionality

For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.

One way to initialize all tooltips on a page would be to select them by their data-toggle attribute:

$(function () {
  $('[data-toggle="tooltip"]').tooltip()
})

Tooltips in button groups and input groups require special setting

When using tooltips on elements within a .btn-group or an .input-group, you'll have to specify the option container: 'body' (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip is triggered).

Don't try to show tooltips on hidden elements

Invoking $(...).tooltip('show') when the target element is display: none; will cause the tooltip to be incorrectly positioned.

Tooltips on disabled elements require wrapper elements

To add a tooltip to a disabled or .disabled element, put the element inside of a <div> and apply the tooltip to that <div> instead.

Usage

The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.

Trigger the tooltip via JavaScript:

$('#example').tooltip(options)

Markup

The required markup for a tooltip is only a data attribute and title on the HTML element you wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to top by the plugin).

Sometimes you want to add a tooltip to a hyperlink that wraps multiple lines. The default behavior of the tooltip plugin is to center it horizontally and vertically. Add white-space: nowrap; to your anchors to avoid this.

Tooltips in button groups, input groups, and tables require special setting

When using tooltips on elements within a .btn-group or an .input-group, or on table-related elements (<td>, <th>, <tr>, <thead>, <tbody>, <tfoot>), you'll have to specify the option container: 'body' (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip is triggered).

Don't try to show tooltips on hidden elements

Invoking $(...).tooltip('show') when the target element is display: none; will cause the tooltip to be incorrectly positioned.

Accessible tooltips for keyboard and assistive technology users

For users navigating with a keyboard, and in particular users of assistive technologies, you should only add tooltips to keyboard-focusable elements such as links, form controls, or any arbitrary element with a tabindex="0" attribute.

Tooltips on disabled elements require wrapper elements

To add a tooltip to a disabled or .disabled element, put the element inside of a <div> and apply the tooltip to that <div> instead.

<!-- HTML to write -->
<a href="#" data-toggle="tooltip" title="Some tooltip text!">Hover over me</a>

<!-- Generated markup by the plugin -->
<div class="tooltip top" role="tooltip">
  <div class="tooltip-arrow"></div>
  <div class="tooltip-inner">
    Some tooltip text!
  </div>
</div>

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-animation="".

Name Type Default Description
animation boolean true Apply a CSS fade transition to the tooltip
container string | false false

Appends the tooltip to a specific element. Example: container: 'body'. This option is particularly useful in that it allows you to position the tooltip in the flow of the document near the triggering element - which will prevent the tooltip from floating away from the triggering element during a window resize.

delay number | object 0

Delay showing and hiding the tooltip (ms) - does not apply to manual trigger type

If a number is supplied, delay is applied to both hide/show

Object structure is: delay: { "show": 500, "hide": 100 }

html boolean false Insert HTML into the tooltip. If false, jQuery's text method will be used to insert content into the DOM. Use text if you're worried about XSS attacks.
placement string | function 'top'

How to position the tooltip - top | bottom | left | right | auto.
When "auto" is specified, it will dynamically reorient the tooltip. For example, if placement is "auto left", the tooltip will display to the left when possible, otherwise it will display right.

When a function is used to determine the placement, it is called with the tooltip DOM node as its first argument and the triggering element DOM node as its second. The this context is set to the tooltip instance.

selector string false If a selector is provided, tooltip objects will be delegated to the specified targets. In practice, this is used to enable dynamic HTML content to have tooltips added. See this and an informative example.
template string '<div class="tooltip" role="tooltip"><div class="tooltip-arrow"></div><div class="tooltip-inner"></div></div>'

Base HTML to use when creating the tooltip.

The tooltip's title will be injected into the .tooltip-inner.

.tooltip-arrow will become the tooltip's arrow.

The outermost wrapper element should have the .tooltip class.

title string | function ''

Default title value if title attribute isn't present.

If a function is given, it will be called with its this reference set to the element that the tooltip is attached to.

trigger string 'hover focus' How tooltip is triggered - click | hover | focus | manual. You may pass multiple triggers; separate them with a space.
viewport string | object { selector: 'body', padding: 0 }

Keeps the tooltip within the bounds of this element. Example: viewport: '#viewport' or { "selector": "#viewport", "padding": 0 }

Data attributes for individual tooltips

Options for individual tooltips can alternatively be specified through the use of data attributes, as explained above.

Methods

$().tooltip(options)

Attaches a tooltip handler to an element collection.

.tooltip('show')

Reveals an element's tooltip. Returns to the caller before the tooltip has actually been shown (i.e. before the shown.bs.tooltip event occurs). This is considered a "manual" triggering of the tooltip. Tooltips with zero-length titles are never displayed.

$('#element').tooltip('show')

.tooltip('hide')

Hides an element's tooltip. Returns to the caller before the tooltip has actually been hidden (i.e. before the hidden.bs.tooltip event occurs). This is considered a "manual" triggering of the tooltip.

$('#element').tooltip('hide')

.tooltip('toggle')

Toggles an element's tooltip. Returns to the caller before the tooltip has actually been shown or hidden (i.e. before the shown.bs.tooltip or hidden.bs.tooltip event occurs). This is considered a "manual" triggering of the tooltip.

$('#element').tooltip('toggle')

.tooltip('destroy')

Hides and destroys an element's tooltip. Tooltips that use delegation (which are created using the selector option) cannot be individually destroyed on descendant trigger elements.

$('#element').tooltip('destroy')

Events

Event Type Description
show.bs.tooltip This event fires immediately when the show instance method is called.
shown.bs.tooltip This event is fired when the tooltip has been made visible to the user (will wait for CSS transitions to complete).
hide.bs.tooltip This event is fired immediately when the hide instance method has been called.
hidden.bs.tooltip This event is fired when the tooltip has finished being hidden from the user (will wait for CSS transitions to complete).
$('#myTooltip').on('hidden.bs.tooltip', function () {
  // do something…
})

Popovers

Add small overlays of content, like those on the iPad, to any element for housing secondary information.

Popovers whose both title and content are zero-length are never displayed.

Plugin dependency

Popovers require the tooltip plugin to be included in your version of Bootstrap.

Opt-in functionality

For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.

One way to initialize all popovers on a page would be to select them by their data-toggle attribute:

$(function () {
  $('[data-toggle="popover"]').popover()
})

Popovers in button groups and input groups require special setting

When using popovers on elements within a .btn-group or an .input-group, you'll have to specify the option container: 'body' (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the popover is triggered).

Don't try to show popovers on hidden elements

Invoking $(...).popover('show') when the target element is display: none; will cause the popover to be incorrectly positioned.

Popovers on disabled elements require wrapper elements

To add a popover to a disabled or .disabled element, put the element inside of a <div> and apply the popover to that <div> instead.

Sometimes you want to add a popover to a hyperlink that wraps multiple lines. The default behavior of the popover plugin is to center it horizontally and vertically. Add white-space: nowrap; to your anchors to avoid this.

Examples

Static popover

Four options are available: top, right, bottom, and left aligned.

Popover top

Lorem ipsum dolor sit inglo amet, con sectetur adi set piscing elit. Sed sit amet orci iaculis, rhoncus neque vitae, tempor justo.

Donec elementum risus in mauris mattis conva llis mus elpementum odio a felis bibendum

Popover right

Lorem ipsum dolor sit inglo amet, con sectetur adi set piscing elit. Sed sit amet orci iaculis, rhoncus neque vitae, tempor justo.

Donec elementum risus in mauris mattis conva llis mus elpementum odio a felis bibendum

Popover bottom

Lorem ipsum dolor sit inglo amet, con sectetur adi set piscing elit. Sed sit amet orci iaculis, rhoncus neque vitae, tempor justo.

Donec elementum risus in mauris mattis conva llis mus elpementum odio a felis bibendum

Popover left

Lorem ipsum dolor sit inglo amet, con sectetur adi set piscing elit. Sed sit amet orci iaculis, rhoncus neque vitae, tempor justo.

Donec elementum risus in mauris mattis conva llis mus elpementum odio a felis bibendum

Live demo

<button type="button" class="btn btn-lg btn-primary" data-toggle="popover" title="Popover title" data-content="And here's some amazing content. It's very engaging. Right?">Click to toggle popover</button>

Four directions

<button type="button" class="btn btn-default" data-container="body" data-toggle="popover" data-placement="left" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
  Popover on left
</button>

<button type="button" class="btn btn-default" data-container="body" data-toggle="popover" data-placement="top" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
  Popover on top
</button>

<button type="button" class="btn btn-default" data-container="body" data-toggle="popover" data-placement="bottom" data-content="Vivamus
sagittis lacus vel augue laoreet rutrum faucibus.">
  Popover on bottom
</button>

<button type="button" class="btn btn-default" data-container="body" data-toggle="popover" data-placement="right" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
  Popover on right
</button>

Dismiss on next click

Use the focus trigger to dismiss popovers on the next click that the user makes.

Specific markup required for dismiss-on-next-click

For proper cross-browser and cross-platform behavior, you must use the <a> tag, not the <button> tag, and you also must include the role="button" and tabindex attributes.

<a tabindex="0" class="btn btn-lg btn-danger" role="button" data-toggle="popover" data-trigger="focus" title="Dismissible popover" data-content="And here's some amazing content. It's very engaging. Right?">Dismissible popover</a>

Usage

Enable popovers via JavaScript:

$('#example').popover(options)

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-animation="".

Name Type Default Description
animation boolean true Apply a CSS fade transition to the popover
container string | false false

Appends the popover to a specific element. Example: container: 'body'. This option is particularly useful in that it allows you to position the popover in the flow of the document near the triggering element - which will prevent the popover from floating away from the triggering element during a window resize.

content string | function ''

Default content value if data-content attribute isn't present.

If a function is given, it will be called with its this reference set to the element that the popover is attached to.

delay number | object 0

Delay showing and hiding the popover (ms) - does not apply to manual trigger type

If a number is supplied, delay is applied to both hide/show

Object structure is: delay: { "show": 500, "hide": 100 }

html boolean false Insert HTML into the popover. If false, jQuery's text method will be used to insert content into the DOM. Use text if you're worried about XSS attacks.
placement string | function 'right'

How to position the popover - top | bottom | left | right | auto.
When "auto" is specified, it will dynamically reorient the popover. For example, if placement is "auto left", the popover will display to the left when possible, otherwise it will display right.

When a function is used to determine the placement, it is called with the popover DOM node as its first argument and the triggering element DOM node as its second. The this context is set to the popover instance.

selector string false If a selector is provided, popover objects will be delegated to the specified targets. In practice, this is used to enable dynamic HTML content to have popovers added. See this and an informative example.
template string '<div class="popover" role="tooltip"><div class="arrow"></div><h3 class="popover-title"></h3><div class="popover-content"></div></div>'

Base HTML to use when creating the popover.

The popover's title will be injected into the .popover-title.

The popover's content will be injected into the .popover-content.

.arrow will become the popover's arrow.

The outermost wrapper element should have the .popover class.

title string | function ''

Default title value if title attribute isn't present.

If a function is given, it will be called with its this reference set to the element that the popover is attached to.

trigger string 'click' How popover is triggered - click | hover | focus | manual. You may pass multiple triggers; separate them with a space.
viewport string | object { selector: 'body', padding: 0 }

Keeps the popover within the bounds of this element. Example: viewport: '#viewport' or { "selector": "#viewport", "padding": 0 }

Data attributes for individual popovers

Options for individual popovers can alternatively be specified through the use of data attributes, as explained above.

Methods

$().popover(options)

Initializes popovers for an element collection.

.popover('show')

Reveals an element's popover. Returns to the caller before the popover has actually been shown (i.e. before the shown.bs.popover event occurs). This is considered a "manual" triggering of the popover. Popovers whose both title and content are zero-length are never displayed.

$('#element').popover('show')

.popover('hide')

Hides an element's popover. Returns to the caller before the popover has actually been hidden (i.e. before the hidden.bs.popover event occurs). This is considered a "manual" triggering of the popover.

$('#element').popover('hide')

.popover('toggle')

Toggles an element's popover. Returns to the caller before the popover has actually been shown or hidden (i.e. before the shown.bs.popover or hidden.bs.popover event occurs). This is considered a "manual" triggering of the popover.

$('#element').popover('toggle')

.popover('destroy')

Hides and destroys an element's popover. Popovers that use delegation (which are created using the selector option) cannot be individually destroyed on descendant trigger elements.

$('#element').popover('destroy')

Events

Event Type Description
show.bs.popover This event fires immediately when the show instance method is called.
shown.bs.popover This event is fired when the popover has been made visible to the user (will wait for CSS transitions to complete).
hide.bs.popover This event is fired immediately when the hide instance method has been called.
hidden.bs.popover This event is fired when the popover has finished being hidden from the user (will wait for CSS transitions to complete).
$('#myPopover').on('hidden.bs.popover', function () {
  // do something…
})

Alert messages

Example alerts

Add dismiss functionality to all alert messages with this plugin.

When using a .close button, it must be the first child of the .alert-dismissible and no text content may come before it in the markup.

Usage

Just add data-dismiss="alert" to your close button to automatically give an alert close functionality. Closing an alert removes it from the DOM.

<button type="button" class="close" data-dismiss="alert" aria-label="Close">
  <span aria-hidden="true">&times;</span>
</button>

To have your alerts use animation when closing, make sure they have the .fade and .in classes already applied to them.

Methods

$().alert()

Makes an alert listen for click events on descendant elements which have the data-dismiss="alert" attribute. (Not necessary when using the data-api's auto-initialization.)

$().alert('close')

Closes an alert by removing it from the DOM. If the .fade and .in classes are present on the element, the alert will fade out before it is removed.

Events

Bootstrap's alert plugin exposes a few events for hooking into alert functionality.

Event Type Description
close.bs.alert This event fires immediately when the close instance method is called.
closed.bs.alert This event is fired when the alert has been closed (will wait for CSS transitions to complete).
$('#myAlert').on('closed.bs.alert', function () {
  // do something…
})

Buttons

Do more with buttons. Control button states or create groups of buttons for more components like toolbars.

Cross-browser compatibility

Firefox persists form control states (disabledness and checkedness) across page loads. A workaround for this is to use autocomplete="off". See Mozilla bug #654072.

Stateful

Add data-loading-text="Loading..." to use a loading state on a button.

This feature is deprecated in Bootstrap v3.3.6 and has been removed in v4.

Use whichever state you like!

For the sake of this demonstration, we are using data-loading-text and $().button('loading'), but that's not the only state you can use. See more on this below in the $().button(string) documentation.

<button type="button" id="myButton" data-loading-text="Loading..." class="btn btn-default" autocomplete="off">
  Loading state
</button>

<script>
  $('#myButton').on('click', function () {
    var $btn = $(this).button('loading')
    // business logic...
    $btn.button('reset')
  })
</script>

Single toggle

Add data-toggle="button" to activate toggling on a single button.

Pre-toggled buttons need .active and aria-pressed="true"

For pre-toggled buttons, you must add the .active class and the aria-pressed="true" attribute to the button yourself.

<button type="button" class="btn btn-default" data-toggle="button" aria-pressed="false" autocomplete="off">
  Single toggle
</button>

Checkbox / Radio Visma

Button groups

Add data-toggle="buttons" to a .btn-group containing checkbox or radio inputs to enable toggling in their respective styles.

Preselected options need .active

For preselected options, you must add the .active class to the input's label yourself.

Visual checked state only updated on click

If the checked state of a checkbox button is updated without firing a click event on the button (e.g. via <input type="reset"> or via setting the checked property of the input), you will need to toggle the .active class on the input's label yourself.

<div class="btn-group" data-toggle="buttons">
  <label class="btn btn-default active">
    <input type="checkbox" autocomplete="off" checked> Checkbox 1 (pre-checked)
  </label>
  <label class="btn btn-default">
    <input type="checkbox" autocomplete="off"> Checkbox 2
  </label>
  <label class="btn btn-default">
    <input type="checkbox" autocomplete="off"> Checkbox 3
  </label>
</div>
<div class="btn-group" data-toggle="buttons">
  <label class="btn btn-default active">
    <input type="radio" name="options" id="option1" autocomplete="off" checked> Radio 1 (preselected)
  </label>
  <label class="btn btn-default">
    <input type="radio" name="options" id="option2" autocomplete="off"> Radio 2
  </label>
  <label class="btn btn-default">
    <input type="radio" name="options" id="option3" autocomplete="off"> Radio 3
  </label>
</div>

Custom checkboxes / radio Visma

Add .btn-group-checkbox or .btn-group-radio to a .btn-group containing checkbox or radio inputs to enable toggling in their respective styles.

<div class="btn-group btn-group-checkbox" data-toggle="buttons">
   ...
</div>
<div class="btn-group btn-group-radio" data-toggle="buttons">
   ...
</div>

Methods

$().button('toggle')

Toggles push state. Gives the button the appearance that it has been activated.

$().button('reset')

Resets button state - swaps text to original text.

$().button(string)

Swaps text to any data defined text state.

<button type="button" id="myStateButton" data-complete-text="finished!" class="btn btn-primary" autocomplete="off">
  ...
</button>

<script>
  $('#myStateButton').on('click', function () {
    $(this).button('complete') // button text will be "finished!"
  })
</script>

Collapse

Flexible plugin that utilizes a handful of classes for easy toggle behavior.

Plugin dependency

Collapse requires the transitions plugin to be included in your version of Bootstrap.

Example

Click the buttons below to show and hide another element via class changes:

  • .collapse hides content
  • .collapsing is applied during transitions
  • .collapse.in shows content

You can use a link with the href attribute, or a button with the data-target attribute. In both cases, the data-toggle="collapse" is required.

Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt sapiente ea proident.
<a class="btn btn-primary" data-toggle="collapse" href="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
  Link with href
</a>
<button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
  Button with data-target
</button>
<div class="collapse" id="collapseExample">
  <div class="well">
    ...
  </div>
</div>

Accordion example

Extend the default collapse behavior to create an accordion with the panel component.

Make expand/collapse controls accessible

Be sure to add aria-expanded to the control element. This attribute explicitly defines the current state of the collapsible element to screen readers and similar assistive technologies. If the collapsible element is closed by default, it should have a value of aria-expanded="false". If you've set the collapsible element to be open by default using the in class, set aria-expanded="true" on the control instead. The plugin will automatically toggle this attribute based on whether or not the collapsible element has been opened or closed.

Additionally, if your control element is targetting a single collapsible element – i.e. the data-target attribute is pointing to an id selector – you may add an additional aria-controls attribute to the control element, containing the id of the collapsible element. Modern screen readers and similar assistive technologies make use of this attribute to provide users with additional shortcuts to navigate directly to the collapsible element itself.

Usage

The collapse plugin utilizes a few classes to handle the heavy lifting:

  • .collapse hides the content
  • .collapse.in shows the content
  • .collapsing is added when the transition starts, and removed when it finishes

These classes can be found in component-animations.less.

Via data attributes

Just add data-toggle="collapse" and a data-target to the element to automatically assign control of a collapsible element. The data-target attribute accepts a CSS selector to apply the collapse to. Be sure to add the class collapse to the collapsible element. If you'd like it to default open, add the additional class in.

To add accordion-like group management to a collapsible control, add the data attribute data-parent="#selector". Refer to the demo to see this in action.

Via JavaScript

Enable manually with:

$('.collapse').collapse()

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-parent="".

Name type default description
parent selector false If a selector is provided, then all collapsible elements under the specified parent will be closed when this collapsible item is shown. (similar to traditional accordion behavior - this is dependent on the panel class)
toggle boolean true Toggles the collapsible element on invocation

Methods

.collapse(options)

Activates your content as a collapsible element. Accepts an optional options object.

$('#myCollapsible').collapse({
  toggle: false
})

.collapse('toggle')

Toggles a collapsible element to shown or hidden.

.collapse('show')

Shows a collapsible element.

.collapse('hide')

Hides a collapsible element.

Events

Bootstrap's collapse class exposes a few events for hooking into collapse functionality.

Event Type Description
show.bs.collapse This event fires immediately when the show instance method is called.
shown.bs.collapse This event is fired when a collapse element has been made visible to the user (will wait for CSS transitions to complete).
hide.bs.collapse This event is fired immediately when the hide method has been called.
hidden.bs.collapse This event is fired when a collapse element has been hidden from the user (will wait for CSS transitions to complete).
$('#myCollapsible').on('hidden.bs.collapse', function () {
  // do something…
})

Carousel

A slideshow component for cycling through elements, like a carousel. Nested carousels are not supported.

<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
  <!-- Indicators -->
  <ol class="carousel-indicators">
    <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
    <li data-target="#carousel-example-generic" data-slide-to="1"></li>
    <li data-target="#carousel-example-generic" data-slide-to="2"></li>
  </ol>

  <!-- Wrapper for slides -->
  <div class="carousel-inner" role="listbox">
    <div class="item active">
      <img src="..." alt="...">
      <div class="carousel-caption">
        ...
      </div>
    </div>
    <div class="item">
      <img src="..." alt="...">
      <div class="carousel-caption">
        ...
      </div>
    </div>
    ...
  </div>

  <!-- Controls -->
  <a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
    <span class="vismaicon vismaicon-arrow-left-circle" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
    <span class="vismaicon vismaicon-arrow-right-circle" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>

Optional captions

Add captions to your slides easily with the .carousel-caption element within any .item. Place just about any optional HTML within there and it will be automatically aligned and formatted.

<div class="item">
  <img src="..." alt="...">
  <div class="carousel-caption">
    <h3>...</h3>
    <p>...</p>
  </div>
</div>

Multiple carousels

Carousels require the use of an id on the outermost container (the .carousel) for carousel controls to function properly. When adding multiple carousels, or when changing a carousel's id, be sure to update the relevant controls.

Via data attributes

Use data attributes to easily control the position of the carousel. data-slide accepts the keywords prev or next, which alters the slide position relative to its current position. Alternatively, use data-slide-to to pass a raw slide index to the carousel data-slide-to="2", which shifts the slide position to a particular index beginning with 0.

The data-ride="carousel" attribute is used to mark a carousel as animating starting at page load. It cannot be used in combination with (redundant and unnecessary) explicit JavaScript initialization of the same carousel.

Via JavaScript

Call carousel manually with:

$('.carousel').carousel()

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-interval="".

Name type default description
interval number 5000 The amount of time to delay between automatically cycling an item. If false, carousel will not automatically cycle.
pause string "hover" Pauses the cycling of the carousel on mouseenter and resumes the cycling of the carousel on mouseleave.
wrap boolean true Whether the carousel should cycle continuously or have hard stops.
keyboard boolean true Whether the carousel should react to keyboard events.

.carousel(options)

Initializes the carousel with an optional options object and starts cycling through items.

$('.carousel').carousel({
  interval: 2000
})

.carousel('cycle')

Cycles through the carousel items from left to right.

.carousel('pause')

Stops the carousel from cycling through items.

.carousel(number)

Cycles the carousel to a particular frame (0 based, similar to an array).

.carousel('prev')

Cycles to the previous item.

.carousel('next')

Cycles to the next item.

Bootstrap's carousel class exposes two events for hooking into carousel functionality.

Both events have the following additional properties:

  • direction: The direction in which the carousel is sliding (either "left" or "right").
  • relatedTarget: The DOM element that is being slid into place as the active item.

All carousel events are fired at the carousel itself (i.e. at the <div class="carousel">).

Event Type Description
slide.bs.carousel This event fires immediately when the slide instance method is invoked.
slid.bs.carousel This event is fired when the carousel has completed its slide transition.
$('#myCarousel').on('slide.bs.carousel', function () {
  // do something…
})

Affix

Example

The affix plugin toggles position: fixed; on and off, emulating the effect found with position: sticky;. The subnavigation on the right is a live demo of the affix plugin.


Usage

Use the affix plugin via data attributes or manually with your own JavaScript. In both situations, you must provide CSS for the positioning and width of your affixed content.

Note: Do not use the affix plugin on an element contained in a relatively positioned element, such as a pulled or pushed column, due to a Safari rendering bug.

Positioning via CSS

The affix plugin toggles between three classes, each representing a particular state: .affix, .affix-top, and .affix-bottom. You must provide the styles, with the exception of position: fixed; on .affix, for these classes yourself (independent of this plugin) to handle the actual positions.

Here's how the affix plugin works:

  1. To start, the plugin adds .affix-top to indicate the element is in its top-most position. At this point no CSS positioning is required.
  2. Scrolling past the element you want affixed should trigger the actual affixing. This is where .affix replaces .affix-top and sets position: fixed; (provided by Bootstrap's CSS).
  3. If a bottom offset is defined, scrolling past it should replace .affix with .affix-bottom. Since offsets are optional, setting one requires you to set the appropriate CSS. In this case, add position: absolute; when necessary. The plugin uses the data attribute or JavaScript option to determine where to position the element from there.

Follow the above steps to set your CSS for either of the usage options below.

Via data attributes

To easily add affix behavior to any element, just add data-spy="affix" to the element you want to spy on. Use offsets to define when to toggle the pinning of an element.

<div data-spy="affix" data-offset-top="60" data-offset-bottom="200">
  ...
</div>

Via JavaScript

Call the affix plugin via JavaScript:

$('#myAffix').affix({
  offset: {
    top: 100,
    bottom: function () {
      return (this.bottom = $('.footer').outerHeight(true))
    }
  }
})

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-offset-top="200".

Name type default description
offset number | function | object 10 Pixels to offset from screen when calculating position of scroll. If a single number is provided, the offset will be applied in both top and bottom directions. To provide a unique, bottom and top offset just provide an object offset: { top: 10 } or offset: { top: 10, bottom: 5 }. Use a function when you need to dynamically calculate an offset.
target selector | node | jQuery element the window object Specifies the target element of the affix.

Methods

.affix(options)

Activates your content as affixed content. Accepts an optional options object.

$('#myAffix').affix({
  offset: 15
})

.affix('checkPosition')

Recalculates the state of the affix based on the dimensions, position, and scroll position of the relevant elements. The .affix, .affix-top, and .affix-bottom classes are added to or removed from the affixed content according to the new state. This method needs to be called whenever the dimensions of the affixed content or the target element are changed, to ensure correct positioning of the affixed content.

$('#myAffix').affix('checkPosition')

Events

Bootstrap's affix plugin exposes a few events for hooking into affix functionality.

Event Type Description
affix.bs.affix This event fires immediately before the element has been affixed.
affixed.bs.affix This event is fired after the element has been affixed.
affix-top.bs.affix This event fires immediately before the element has been affixed-top.
affixed-top.bs.affix This event is fired after the element has been affixed-top.
affix-bottom.bs.affix This event fires immediately before the element has been affixed-bottom.
affixed-bottom.bs.affix This event is fired after the element has been affixed-bottom.
