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

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>

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>

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>
  ...
</ul>

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="navbar-form pull-left">
  <input type="text" class="span2">
  <button type="submit" class="btn">Submit</button>
</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.

<form class="navbar-search pull-left">
  <input type="text" class="search-query" placeholder="Search">
</form>

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.

Add dropdowns and dropups to the nav with a bit of markup and the .

    <li><a href="#">3</a></li>
    <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">
  <ul>
    <li class="disabled"><span>Prev</span></li>
    <li class="active"><span>1</span></li>
