Examples

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 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-hidden="true">&times;</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-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
</div><!-- /.modal -->

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.

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="".

Name type default description
backdrop boolean 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

If a remote URL is provided, content will be loaded via jQuery's load method and injected into the root of the modal element. 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.

$('#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.

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

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

Within a navbar

Within tabs

Via data attributes

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

<div class="dropdown">
  <a 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 id="dLabel" role="button" data-toggle="dropdown" data-target="#" href="/page.html">
    Dropdown <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()

Options

None

Methods

$().dropdown('toggle')

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

Events

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…
})

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.

<!-- Nav tabs -->
<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>

<!-- Tab panes -->
<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>

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

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

Example alerts

Add dismiss functionality to all alert messages with this plugin.

Holy guacamole! Best check yo self, you're not looking too good.

Focus Management :
When the alert is dismissed with keyboard make sure the focus is transferred back to the element which fired this alert, or otherwise the screen reader may enter into freakout mode

Oh snap! You got an error!

Change this and that and try again. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Cras mattis consectetur purus sit amet fermentum.

Focus Management :
When the alert is dismissed with keyboard make sure the focus is transferred back to the element which fired this alert, or otherwise the screen reader may enter into freakout mode

Usage

Enable dismissal of an alert via JavaScript:

$(".alert").alert()

Markup

Just add data-dismiss="alert" to your close button to automatically give an alert close functionality.

<a class="close" data-dismiss="alert" href="#" aria-hidden="true">&times;</a>

Methods

$().alert()

Wraps all alerts with close functionality. To have your alerts animate out when closed, make sure they have the .fade and .in class already applied to them.

.alert('close')

Closes an alert.

$(".alert").alert('close')

Events

Bootstrap's alert class 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).
$('#my-alert').bind('closed.bs.alert', function () {
  // do something…
})

About

Get base styles and flexible support for collapsible components like accordions and navigation.

Plugin dependency

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

Example accordion

Using the collapse plugin, we built a simple accordion by extending the panel component.

You can also use the plugin without the accordion markup. Make a button toggle the expanding and collapsing of another element.

<button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#demo">
  simple collapsible
</button>

<div id="demo" class="collapse in">...</div>

Usage

Via data attributes

Just add data-toggle="collapse" and a data-target to 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 selector then all collapsible elements under the specified parent will be closed when this collapsible item is shown. (similar to traditional accordion behavior - this dependent on the accordion-group 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…
})

The slideshow below shows a generic plugin and component for cycling through elements like a carousel.

<div id="carousel-example-generic" class="carousel slide">
  <!-- 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">
    <div class="item active">
      <img src="..." alt="...">
      <div class="carousel-caption">
        ...
      </div>
    </div>
    ...
  </div>

  <!-- Controls -->
  <a class="left carousel-control" href="#carousel-example-generic" data-slide="prev">
    <span class="glyphicon glyphicon-chevron-left"></span>
  </a>
  <a class="right carousel-control" href="#carousel-example-generic" data-slide="next">
    <span class="glyphicon glyphicon-chevron-right"></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 active">
  <img src="..." alt="...">
  <div class="carousel-caption">
    <h3>...</h3>
    <p>...</p>
  </div>
</div>

Accessibility issue

The carousel component is generally not compliant with accessibility standards. If you need to be compliant, please consider other options for presenting your content.
Please visit http://shouldiuseacarousel.com/ for more details

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.

Via JavaScript

Call carousel manually with:

$('.carousel').carousel()

Options

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.

Methods

.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.

Events

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

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…
})
