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

  <li class="divider"></li>
  <li><a tabindex="-1" href="#">Separated link</a></li>
</ul>

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>

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.

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">Dropup</button>
  <button class="btn dropdown-toggle" data-toggle="dropdown">

  </li>
  <li><a href="#">...</a></li>

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>

For any nav component (tabs, pills, or list), add .disabled for gray links and no hover effects. Links will remain clickable, however, unless custom javascript is implemented to prevent those clicks.

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

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

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">
  <div class="navbar-inner">
    <a class="brand" href="#">Title</a>
    <ul class="nav">
      <li class="active"><a href="#">Home</a></li>

      <li><a href="#">Link</a></li>
    </ul>
  </div>
</div>

A simple link to show your brand or project name only requires an anchor tag.

<a class="brand" href="#">Project name</a>

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 this between links:

<ul class="nav">

  <li class="divider-vertical"></li>

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.

    <li><a href="#">4</a></li>
    <li><a href="#">Next</a></li>
  </ul>
</div>

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>

You can optionally swap out active or disabled anchors for spans to remove click functionality while retaining intended styles.

<div class="pagination">

    <li class="disabled"><span>Prev</span></li>
    <li class="active"><span>1</span></li>

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">

    <a href="#" class="thumbnail">
      <img src="http://placehold.it/300x200" alt="">
    </a>
  </li>
  ...
</ul>

For custom HTML content in thumbnails, the markup changes slightly. To allow block level content anywhere, we swap the <a> for a <div> like so:

<ul class="thumbnails">
  <li class="span4">
    <div class="thumbnail">
      <img src="http://placehold.it/300x200" alt="">
      <h3>Thumbnail label</h3>
      <p>Thumbnail caption...</p>
