Individual or compiled

Plugins can be included individually (though some have required dependencies), or all at once. Both bootstrap.js and bootstrap.min.js contain all plugins in a single file.

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 body namespaced with `'data-api'`. This looks like this:

$('body').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:

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

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').

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 plugin's 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 trigger on the completion of an action.

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

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

About transitions

For simple transition effects, include bootstrap-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.

Use cases

A few examples of the transition plugin:

• Sliding or fading in modals
• Fading out tabs
• Fading out alerts
• Sliding carousel panes

Examples

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

Static example

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

<div class="modal hide fade">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
    <h3>Modal header</h3>
  </div>
  <div class="modal-body">
    <p>One fine body…</p>
  </div>
  <div class="modal-footer">
    <a href="#" class="btn">Close</a>
    <a href="#" class="btn btn-primary">Save changes</a>
  </div>
</div>

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 to trigger modal -->
<a href="#myModal" role="button" class="btn" data-toggle="modal">Launch demo modal</a>

<!-- Modal -->
<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
    <h3 id="myModalLabel">Modal header</h3>
  </div>
  <div class="modal-body">
    <p>One fine body…</p>
  </div>
  <div class="modal-footer">
    <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
    <button class="btn btn-primary">Save changes</button>
  </div>
</div>

Usage

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="".

<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.

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

.modal('show')

Manually opens a modal.

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

.modal('hide')

Manually hides a modal.

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

Events

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

$('#myModal').on('hidden', function () {
  // do something…
})

Examples

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

Within a navbar

Within tabs

Usage

Via data attributes

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

<div class="dropdown">
  <a class="dropdown-toggle" data-toggle="dropdown" href="#">Dropdown trigger</a>
  <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
    ...
  </ul>
</div>

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

<div class="dropdown">
  <a class="dropdown-toggle" id="dLabel" role="button" data-toggle="dropdown" data-target="#" href="/page.html">
    Dropdown
    <b class="caret"></b>
  </a>
  <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
    ...
  </ul>
</div>

Via JavaScript

Call the dropdowns via JavaScript:

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

Options

None

Methods

$().dropdown('toggle')

A programmatic api for toggling menus for a given navbar or tabbed navigation.

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

Via data attributes

To easily add scrollspy behavior to your topbar navigation, just add data-spy="scroll" to the element you want to spy on (most typically this would be the body) and data-target=".navbar" to select which nav to use. You'll want to use scrollspy with a .nav component.

<body data-spy="scroll" data-target=".navbar">...</body>

Via JavaScript

Call the scrollspy via JavaScript:

$('#navbar').scrollspy()

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="".

Events

Example tabs

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

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.

<ul class="nav nav-tabs">
  <li><a href="#home" data-toggle="tab">Home</a></li>
  <li><a href="#profile" data-toggle="tab">Profile</a></li>
  <li><a href="#messages" data-toggle="tab">Messages</a></li>
  <li><a href="#settings" data-toggle="tab">Settings</a></li>
</ul>

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" id="myTab">
  <li class="active"><a href="#home">Home</a></li>
  <li><a href="#profile">Profile</a></li>
  <li><a href="#messages">Messages</a></li>
  <li><a href="#settings">Settings</a></li>
</ul>

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

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

Events

$('a[data-toggle="tab"]').on('shown', function (e) {
  e.target // activated tab
  e.relatedTarget // previous tab
})

Examples

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.

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

Hover over the links below to see tooltips:

Four directions

Tooltips in input groups

When using tooltips and popovers with the Bootstrap input groups, you'll have to set the container (documented below) option to avoid unwanted side effects.

Usage

Trigger the tooltip via JavaScript:

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

Options

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

Markup

<a href="#" data-toggle="tooltip" title="first tooltip">hover over me</a>

Methods

$().tooltip(options)

Attaches a tooltip handler to an element collection.

.tooltip('show')

Reveals an element's tooltip.

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

.tooltip('hide')

Hides an element's tooltip.

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

.tooltip('toggle')

Toggles an element's tooltip.

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

.tooltip('destroy')

Hides and destroys an element's tooltip.

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

Examples

Add small overlays of content, like those on the iPad, to any element for housing secondary information. Hover over the button to trigger the popover. Requires Tooltip to be included.

Static popover

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

No markup shown as popovers are generated from JavaScript and content within a data attribute.

Live demo

Four directions

Usage

Enable popovers via JavaScript:

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