Example

Toggleable, contextual menu for displaying lists of links. Made interactive with the dropdown JavaScript plugin.

<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu">
  <li><a tabindex="-1" href="#">Action</a></li>
  <li><a tabindex="-1" href="#">Another action</a></li>
  <li><a tabindex="-1" href="#">Something else here</a></li>
  <li class="divider"></li>
  <li><a tabindex="-1" href="#">Separated link</a></li>
</ul>

Markup

Looking at just the dropdown menu, here's the required HTML. You need to wrap the dropdown's trigger and the dropdown menu within .dropdown, or another element that declares position: relative;. Then just create the menu.

<div class="dropdown">
  <!-- Link or button to toggle dropdown -->
  <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
    <li><a tabindex="-1" href="#">Action</a></li>
    <li><a tabindex="-1" href="#">Another action</a></li>
    <li><a tabindex="-1" href="#">Something else here</a></li>
    <li class="divider"></li>
    <li><a tabindex="-1" href="#">Separated link</a></li>
  </ul>
</div>

Options

Align menus to the right and add include additional levels of dropdowns.

Aligning the menus

Add .pull-right to a .dropdown-menu to right align the dropdown menu.

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

Disabled menu options

Add .disabled to a <li> in the dropdown to disable the link.

<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu">
  <li><a tabindex="-1" href="#">Regular link</a></li>
  <li class="disabled"><a tabindex="-1" href="#">Disabled link</a></li>
  <li><a tabindex="-1" href="#">Another link</a></li>
</ul>

Sub menus on dropdowns

Add an extra level of dropdown menus, appearing on hover like those of OS X, with some simple markup additions. Add .dropdown-submenu to any li in an existing dropdown menu for automatic styling.

<ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
  ...
  <li class="dropdown-submenu">
    <a tabindex="-1" href="#">More options</a>
    <ul class="dropdown-menu">
      ...
    </ul>
  </li>
</ul>

Examples

Two basic options, along with two more specific variations.

Single button group

Wrap a series of buttons with .btn in .btn-group.

<div class="btn-group">
	<button class="btn"> ... </button>
	<button class="btn"> ... </button>
	...
</div>

Multiple button groups

Combine sets of <div class="btn-group"> into a <div class="btn-toolbar"> for more complex components.

<div class="btn-toolbar">
	<div class="btn-group">
		<button class="btn"> ... </button>
		...
	</div>
	<div class="btn-group">
		<button class="btn"> ... </button>
		...
	</div>
</div>

Vertical button groups

Make a set of buttons appear vertically stacked rather than horizontally.

<div class="btn-group btn-group-vertical">
	<button class="btn"> ... </button>
	<button class="btn"> ... </button>
	...
</div>

Overview and examples

Use any button to trigger a dropdown menu by placing it within a .btn-group and providing the proper menu markup.

<div class="btn-group">
 <a class="btn dropdown-toggle" data-toggle="dropdown" href="#">
   Action
   <i class="caret icon-chevron-down"></i>
 </a>
 <ul class="dropdown-menu">
   <!-- dropdown menu links -->
 </ul>
</div>

Works with all button sizes

Button dropdowns work at any size: .btn-large, .btn-small, or .btn-mini.

Requires JavaScript

Button dropdowns require the Bootstrap dropdown plugin to function.

In some cases—like mobile—dropdown menus will extend outside the viewport. You need to resolve the alignment manually or with custom JavaScript.

Split button dropdowns

Building on the button group styles and markup, we can easily create a split button. Split buttons feature a standard action on the left and a dropdown toggle on the right with contextual links.

<div class="btn-group">
 <button class="btn">Action</button>
 <button class="btn dropdown-toggle" data-toggle="dropdown">
   <i class="caret  icon-chevron-down"></i>
 </button>
 <ul class="dropdown-menu">
   <!-- dropdown menu links -->
 </ul>
</div>

Sizes

Utilize the extra button classes .btn-mini, .btn-small, or .btn-large for sizing.

<div class="btn-group">
	<button class="btn btn-large">Large action</button>
	<button class="btn btn-large dropdown-toggle" data-toggle="dropdown">
		<i class="caret icon-chevron-down"></i>
	</button>
	<ul class="dropdown-menu">
		<!-- dropdown menu links -->
	</ul>
</div>

Dropup menus

Dropdown menus can also be toggled from the bottom up by adding a single class to the immediate parent of .dropdown-menu. It will flip the direction of the .caret and reposition the menu itself to move from the bottom up instead of top down.

<div class="btn-group dropup">
	<button class="btn btn-large">Large action</button>
	<button class="btn btn-large dropdown-toggle" data-toggle="dropdown">
		<i class="caret icon-chevron-up"></i>
	</button>
	<ul class="dropdown-menu">
		<!-- dropdown menu links -->
	</ul>
</div>

Lightweight defaults Same markup, different classes

All nav components here—tabs, pills, and lists—share the same base markup and styles through the .nav class.

Basic tabs

Take a regular <ul> of links and add .nav-tabs:

<ul class="nav nav-tabs">
 <li class="active">
   <a href="#">Home</a>
 </li>
 <li><a href="#">...</a></li>
 <li><a href="#">...</a></li>
</ul>

Basic pills

Take that same HTML, but use .nav-pills instead:

<ul class="nav nav-pills">
 <li class="active">
   <a href="#">Home</a>
 </li>
 <li><a href="#">...</a></li>
 <li><a href="#">...</a></li>
</ul>

Disabled state

For any nav component (tabs, pills, or list), add .disabled for gray links and no hover effects. Links will remain clickable, however, unless you remove the href attribute. Alternatively, you could implement custom JavaScript to prevent those clicks.

<ul class="nav nav-pills">
 ...
 <li class="disabled"><a href="#">Home</a></li>
 ...
</ul>

Component alignment

To align nav links, use the .pull-left or .pull-right utility classes. Both classes will add a CSS float in the specified direction.

Stackable

As tabs and pills are horizontal by default, just add a second class, .nav-stacked, to make them appear vertically stacked.

Stacked tabs

<ul class="nav nav-tabs nav-stacked">
 ...
</ul>

Stacked pills

<ul class="nav nav-pills nav-stacked">
 ...
</ul>

Dropdowns

Add dropdown menus with a little extra HTML and the dropdowns JavaScript plugin.

Tabs with dropdowns

<ul class="nav nav-tabs">
 <li class="dropdown">
   <a class="dropdown-toggle" data-toggle="dropdown" href="#">
       Dropdown
       <b class="caret"></b>
     </a>
   <ul class="dropdown-menu">
     <!-- links -->
   </ul>
 </li>
</ul>

Pills with dropdowns

<ul class="nav nav-pills">
 <li class="dropdown">
   <a class="dropdown-toggle"
      data-toggle="dropdown"
      href="#">
       Dropdown
       <b class="caret"></b>
     </a>
   <ul class="dropdown-menu">
     <!-- links -->
   </ul>
 </li>
</ul>

Nav lists

A simple and easy way to build groups of nav links with optional headers. They're best used in sidebars like the Finder in OS X.

<ul class="nav nav-list">
 <li class="nav-header">List header</li>
 <li class="active"><a href="#">Home</a></li>
 <li><a href="#">Library</a></li>
 ...
</ul>

Note For nesting within a nav list, include class="nav nav-list" on any nested <ul>.

Horizontal dividers

Add a horizontal divider by creating an empty list item with the class .divider, like so:

Tabbable nav

Bring your tabs to life with a simple plugin to toggle between content via tabs. Bootstrap integrates tabbable tabs in four styles: top (default), right, bottom, and left.

Tabbable example

To make tabs tabbable, create a .tab-pane with unique ID for every tab and wrap them in .tab-content.

<div class="tabbable"> <!-- Only required for left/right tabs -->
 <ul class="nav nav-tabs">
   <li class="active"><a href="#tab1" data-toggle="tab">Section 1</a></li>
   <li><a href="#tab2" data-toggle="tab">Section 2</a></li>
 </ul>
 <div class="tab-content">
   <div class="tab-pane active" id="tab1">
     <p>I'm in Section 1.</p>
   </div>
   <div class="tab-pane" id="tab2">
     <p>Howdy, I'm in Section 2.</p>
   </div>
 </div>
</div>

Fade in tabs

To make tabs fade in, add .fade to each .tab-pane.

Requires jQuery plugin

All tabbable tabs are powered by our lightweight jQuery plugin. Read more about how to bring tabbable tabs to life on the JavaScript docs page.

Tabblable in any direction

Tabs on the bottom

Flip the order of the HTML and add a class to put tabs on the bottom.

<div class="tabbable tabs-below">
 <div class="tab-content">
   ...
 </div>
 <ul class="nav nav-tabs">
   ...
 </ul>
</div>

Tabs on the left

Swap the class to put tabs on the left.

<div class="tabbable tabs-left">
 <ul class="nav nav-tabs">
   ...
 </ul>
 <div class="tab-content">
   ...
 </div>
</div>

Tabs on the right

Swap the class to put tabs on the right.

<div class="tabbable tabs-right">
 <ul class="nav nav-tabs">
   ...
 </ul>
 <div class="tab-content">
   ...
 </div>
</div>

Basic navbar

To start, navbars are static (not fixed to the top) and include support for a project name and basic navigation. Place one anywhere within a .container, which sets the width of your site and content.

<header class="navbar">
  <div class="navbar-inner">
    <a class="brand" href="#"><i class="icon-globe"></i> Project Title</a>
    <ul class="nav">
      <li class="active"><a href="#"><i class="icon-home"></i> Home</a></li>
      <li><a href="#"><i class="icon-tag"></i> Link</a></li>
      <li><a href="#"><i class="icon-book"></i> Link</a></li>
      <li class="divider-vertical"></li>
      <li><a href="#"><i class="icon-cogs"></i> Link</a></li>
    </ul>
  </div>
</header>

Navbar components

Forms

To properly style and position a form within the navbar, add the appropriate classes as shown below. For a default form, include .navbar-form and either .pull-left or .pull-right to properly align it.

<header class="navbar">
  <div class="navbar-inner">
    <form class="navbar-form pull-left">
      <input type="text" class="span2" placeholder="input here..." />
      <select name="select" class="span2">
      ...
      <button type="submit" class="btn"><i class="icon-ok"></i></button>
    </form>
  </div>
</header>

Search form

For a more customized search form, add .navbar-search to the form and .search-query to the input for specialized styles in the navbar.

<header class="navbar">
  <div class="navbar-inner">
    <form class="navbar-search pull-left">
      <input type="search" class="search-query" placeholder="Search..." />
    </form>
  </div>
</header>

Examples

A single example shown as it might be displayed across multiple pages.

<ul class="breadcrumb">
 <li><a href="#">Home</a> <span class="divider">/</span></li>
 <li><a href="#">Library</a> <span class="divider">/</span></li>
 <li class="active">Data</li>
</ul>

Standard pagination

Simple pagination inspired by Rdio, great for apps and search results. The large block is hard to miss, easily scalable, and provides large click areas.

<div class="pagination">
  <ul>
    <li><a href="#">Prev</a></li>
    <li><a href="#">1</a></li>
    <li><a href="#">2</a></li>
    <li><a href="#">3</a></li>
    <li><a href="#">4</a></li>
    <li><a href="#">5</a></li>
    <li><a href="#">Next</a></li>
  </ul>
</div>

Options

Disabled and active states

Links are customizable for different circumstances. Use .disabled for unclickable links and .active to indicate the current page.

<div class="pagination">
 <ul>
   <li class="disabled"><a href="#">Prev</a></li>
   <li class="active"><a href="#">1</a></li>
   ...
 </ul>
</div>

Sizes

Fancy larger or smaller pagination? Add .pagination-large, .pagination-small, or .pagination-mini for additional sizes.

<div class="pagination pagination-large">
 <ul>
   ...
 </ul>
</div>
<div class="pagination">
 <ul>
   ...
 </ul>
</div>
<div class="pagination pagination-small">
 <ul>
   ...
 </ul>
</div>
<div class="pagination pagination-mini">
 <ul>
   ...
 </ul>
</div>

Pager

Quick previous and next links for simple pagination implementations with light markup and styles. It's great for simple sites like blogs or magazines.

Default example

By default, the pager centers links.

<ul class="pager">
 <li><a href="#">Previous</a></li>
 <li><a href="#">Next</a></li>
</ul>

Aligned links

Alternatively, you can align each link to the sides:

<ul class="pager">
 <li class="previous">
   <a href="#">Older</a>
 </li>
 <li class="next">
   <a href="#">Newer</a>
 </li>
</ul>

Optional disabled state

Pager links also use the general .disabled utility class from the pagination.

<ul class="pager">
 <li class="previous disabled">
   <a href="#">Older</a>
 </li>
 ...
</ul>

Labels

Badges

Easily collapsible

For easy implementation, labels and badges will simply collapse (via CSS's :empty selector) when no content exists within.

Hero unit

A lightweight, flexible component to showcase key content on your site. It works well on marketing and content-heavy sites.

<div class="hero-unit">
 <h1>Heading</h1>
 <p>Tagline</p>
 <p>
   <a class="btn btn-primary btn-large">
     Learn more...
   </a>
 </p>
</div>

Page header

A simple shell for an h1 to appropriately space out and segment sections of content on a page. It can utilize the h1's default small, element as well most other components (with additional styles).

<div class="page-header">
 <h1>Example page header <small>Subtext for header</small></h1>
</div>

Default thumbnails

By default, Bootstrap's thumbnails are designed to showcase linked images with minimal required markup.

Why use thumbnails

Thumbnails (previously .media-grid up until v1.4) are great for grids of photos or videos, image search results, retail products, portfolios, and much more. They can be links or static content.

Simple, flexible markup

Thumbnail markup is simple—a ul with any number of li elements is all that is required. It's also super flexible, allowing for any type of content with just a bit more markup to wrap your contents.

Uses grid column sizes

Lastly, the thumbnails component uses existing grid system classes—like .span2 or .span3—for control of thumbnail dimensions.

Markup

As mentioned previously, the required markup for thumbnails is light and straightforward. Here's a look at the default setup for linked images:

<ul class="thumbnails">
  <li>
    <a href="#" class="thumbnail">
      <img src="img/img1.jpg" alt="img1" />
    </a>
  </li>
  ...
</ul>

More examples

Explore all your options with the various grid classes available to you. You can also mix and match different sizes.

Default alert

Wrap any text and an optional dismiss button in .alert for a basic warning alert message.

<div class="alert">
 <button type="button" class="close" data-dismiss="alert"></button>
 <strong>Warning!</strong> Best check yo self, you're not looking too good.
</div>

Dismiss buttons

Mobile Safari and Mobile Opera browsers, in addition to the data-dismiss="alert" attribute, require an href="#" for the dismissal of alerts when using an <a> tag.

<a href="#" class="close" data-dismiss="alert"></a>

Alternatively, you may use a <button> element with the data attribute, which we have opted to do for our docs. When using <button>, you must include type="button" or your forms may not submit.

<button type="button" class="close" data-dismiss="alert"></button>

Dismiss alerts via JavaScript

Use the alerts jQuery plugin for quick and easy dismissal of alerts.

Options

For longer messages, increase the padding on the top and bottom of the alert wrapper by adding .alert-block.

<div class="alert alert-block">
 <button type="button" class="close" data-dismiss="alert"></button>
 <h4>Warning!</h4>
 Best check yo self, you're not...
</div>

Contextual alternatives

Add optional classes to change an alert's connotation.

Error or danger

<div class="alert alert-error">
 ...
</div>

Success

<div class="alert alert-success">
 ...
</div>

Information

<div class="alert alert-info">
 ...
</div>

Examples and markup

Basic

Default progress bar with a vertical gradient.

<div class="progress">
 <div class="bar" style="width: 60%;"></div>
</div>

Indeterminate

Use this style for tasks that are not determinate that are non-modal (don't block user interaction).

<div class="progress progress-indeterminate">
 <div class="bar"></div>
</div>

Indeterminate Ring

Use this style for tasks that are not determinate that are non-modal (don't block user interaction).

<div class="progress progress-indeterminate">
 <div class="pulse"></div>
</div>

Stacked

Place multiple bars into the same .progress to stack them.

<div class="progress">
 <div class="bar bar-success" style="width: 35%;"></div>
 <div class="bar bar-warning" style="width: 20%;"></div>
 <div class="bar bar-danger" style="width: 10%;"></div>
</div>

Options

Additional colors

Progress bars use some of the same button and alert classes for consistent styles.

<div class="progress progress-info">
 <div class="bar" style="width: 20%"></div>
</div>
<div class="progress progress-success">
 <div class="bar" style="width: 40%"></div>
</div>
<div class="progress progress-warning">
 <div class="bar" style="width: 60%"></div>
</div>
<div class="progress progress-danger">
 <div class="bar" style="width: 80%"></div>
</div>

Browser support

Progress bars use CSS3 gradients, transitions, and animations to achieve all their effects. These features are not supported in IE7-9 or older versions of Firefox.

Versions earlier than Internet Explorer 10 and Opera 12 do not support animations.

Abstract object styles for building various types of components (like blog comments, Tweets, etc) that feature a left- or right-aligned image alongside textual content.

Default example

The default media allow to float a media object (images, video, audio) to the left or right of a content block.

Media heading

Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.

Media heading

Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.

Media heading

Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin commodo. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.

<div class="media">
 <a class="pull-left" href="#">
   <img class="media-object" src="http://placehold.it/64x64">
 </a>
 <div class="media-body">
   <h4 class="media-heading">Media heading</h4>
   ...

   <!-- Nested media object -->
   <div class="media">
     ...
   </div>
 </div>
</div>

Media list

With a bit of extra markup, you can use media inside list (useful for comment threads or articles lists).

<ul class="media-list">
 <li class="media">
   <a class="pull-left" href="#">
     <img class="media-object" src="http://placehold.it/64x64">
   </a>
   <div class="media-body">
     <h4 class="media-heading">Media heading</h4>
     ...

     <!-- Nested media object -->
     <div class="media">
       ...
    </div>
   </div>
 </li>
</ul>
