- Toggleable, contextual menu for displaying lists of links. Made interactive with the dropdown JavaScript plugin.
-
- Example
- Wrap the dropdown's trigger and the dropdown menu within .dropdown
, or another element that declares position: relative;
. Then add the menu's HTML.
-
-
-<div class="dropdown">
- <!-- Link or button to toggle dropdown -->
- <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>
-</div>
-
-
- 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>

-
- Navs available in Bootstrap have shared markup, starting with the base .nav
class, as well as shared states. Swap modifier classes to switch between each style.
-
- Tabs
- Note the .nav-tabs
class requires the .nav
base class.
-
-
-<ul class="nav nav-tabs">
- <li class="active">
- <a href="#">Home</a>
- </li>
- <li><a href="#">...</a></li>
- <li><a href="#">...</a></li>
-</ul>
-
-
- List
- Swap the tabs class for .nav-list
.
-
-
-<ul class="nav nav-list">
- <li class="active">
- <a href="#">Home</a>
- </li>
- <li><a href="#">...</a></li>
- <li><a href="#">...</a></li>
-</ul>
-
-
- 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>
-
- Pills are also vertically stackable. Just add .nav-stacked
.
-
-
-<ul class="nav nav-pills nav-stacked">
- ...
-</ul>
-
-
- Options
-
- Justified links
- Easily make tabs or pills equal widths of their parent with .nav-justified
.
-
-
-<ul class="nav nav-tabs nav-justified">
- ...
-</ul>
-
-<ul class="nav nav-pills nav-justified">
- ...
-</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.
-
-
-
-
-
- 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">

- </li>
-</ul>

-
- 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.
-
-
-<div class="navbar">
- <a class="brand" href="#">Title</a>
- <ul class="nav">
- <li class="active"><a href="#">Home</a></li>
- <li><a href="#">Link</a></li>
- <li><a href="#">Link</a></li>
- </ul>
-</div>
-
-
-
-
-
-
- Navbar components
-
- Brand
- A simple link to show your brand or project name only requires an anchor tag.
-
-
-<a class="brand" href="#">Project name</a>
-
-
- Nav links
- Nav items are simple to add via unordered lists.
-
-
-<ul class="nav">
- <li class="active">
- <a href="#">Home</a>
- </li>
- <li><a href="#">Link</a></li>
- <li><a href="#">Link</a></li>
-</ul>
-
- You can easily add dividers to your nav links with an empty list item and a simple class. Just add the appropriate class to <li>
elements between links. Dividers will be horizontal to start, but at resolutions above 768px they become vertical with the navigation.
-
-
-<ul class="nav">
- ...
- <li class="divider"></li>
- ...
-</ul>
-
-
- 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.
-
-
-<form class="pull-left">
- <input type="text" style="width: 200px;">
- <button type="submit" class="btn">Submit</button>
-</form>
-
-
- Component alignment
- Align nav links, search form, or text, use the .pull-left
or .pull-right
utility classes. Both classes will add a CSS float in the specified direction.
-
- Using dropdowns
- Add dropdowns and dropups to the nav with a bit of markup and the dropdowns JavaScript plugin.
-
-<ul class="nav">
- <li class="dropdown">
- <a href="#" class="dropdown-toggle" data-toggle="dropdown">
- Account
- <b class="caret"></b>
- </a>
- <ul class="dropdown-menu">
- ...
- </ul>
- </li>
-</ul>
-
- Visit the JavaScript dropdowns documentation for more markup and information on calling dropdowns.
-
- Text
- Wrap strings of text in an element with .navbar-text
, usually on a <p>
tag for proper leading and color.
-
-
-
-
-
- Optional display variations
- Fix the navbar to the top or bottom of the viewport with an additional class on the outermost div, .navbar
.
-
- Fixed to top
- Add .navbar-fixed-top
and remember to account for the hidden area underneath it by adding at least 40px padding
to the <body>
. Be sure to add this after the core Bootstrap CSS and before the optional responsive CSS.
-
-
-<div class="navbar navbar-fixed-top">
- ...
-</div>
-
-
- Fixed to bottom
- Add .navbar-fixed-bottom
instead.
-
-
-<div class="navbar navbar-fixed-bottom">
- ...
-</div>
-
-
- Static top navbar
- Create a full-width navbar that scrolls away with the page by adding .navbar-static-top
. Unlike the .navbar-fixed-top
class, you do not need to change any padding on the body
.
-
-
-<div class="navbar navbar-static-top">
- ...
-</div>
-
-
-
-
-
-
- Responsive navbar
- To implement a collapsing responsive navbar, wrap your navbar content in a containing div, .nav-collapse.collapse
, and add the navbar toggle button, .btn-navbar
.
-
-
-<div class="navbar">
- <div class="container">
-
- <!-- .btn-navbar is used as the toggle for collapsed navbar content -->
- <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
- <span class="icon-bar"></span>
- <span class="icon-bar"></span>
- <span class="icon-bar"></span>
- </a>
-
- <!-- Be sure to leave the brand out there if you want it shown -->
- <a class="brand" href="#">Project name</a>
-
- <!-- Everything you want hidden at 940px or less, place within here -->
- <div class="nav-collapse collapse">
- <!-- .nav, .navbar-search, .navbar-form, etc -->
- </div>
-
- </div>
-</div>
-
-
-
-
-
-
-
- Inverted variation
- Modify the look of the navbar by adding .navbar-inverse
.
-
-
-<div class="navbar navbar-inverse">
- ...
-</div>
-
-
-
-
-
-
-
-
-
- Indicate the current page's location within a navigational hierarchy.
-
-
-
-<ul class="breadcrumb">
- <li><a href="#">Home</a></li>
- <li><a href="#">Library</a></li>
- <li class="active">Data</li>
-</ul>
-
-
-
-
-
-
-
-
-
-
-
-
-
-
- Easily highlight new or unread items by adding a <span class="counter">
to links, Bootstrap navs, and more.
-
-
-
-<a href="#">
- Inbox
- <span class="counter">42</span>
-</a>
-
-
- Self collapsing
- When there are no new or unread items, counters will simply collapse (via CSS's :empty
selector) provided no content exists within.
-
- Adapts to active nav states
- Built-in styles are included for placing counters in active states in pill and list navigations.
-
-
-<ul class="nav nav-list">
- <li class="active">
- <a href="#">Home</a>
- </li>
- <li><a href="#">...</a></li>
- <li><a href="#">...</a></li>
-</ul>
