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. Dropdown menus can be changed to expand upwards (instead of downwards) by adding .dropup to the parent.

<div class="dropdown">
    <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-expanded="true">
        Dropdown
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1">
        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Action</a></li>
        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Another action</a></li>
        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Something else here</a></li>
        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Separated link</a></li>
    </ul>
</div>
<div class="dropup">
    <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu2" data-toggle="dropdown" aria-expanded="true">
        Dropup
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu2">
        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Action</a></li>
        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Another action</a></li>
        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Something else here</a></li>
        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Separated link</a></li>
    </ul>
</div>

Headers

Add a header to label sections of actions in any dropdown menu.

<div class="dropdown">
    <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-expanded="true">
        Dropdown
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1">
        <li role="presentation" class="dropdown-header">Dropdown header</li>
        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Action</a></li>
        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Another action</a></li>
    </ul>
</div>

Divider

Add a divider to separate series of links in a dropdown menu.

<div class="dropdown">
    <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-expanded="true">
        Dropdown
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1">
        <li role="presentation" class="dropdown-header">Dropdown header</li>
        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Action</a></li>
        <li role="presentation" class="divider"></li>
        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Another action</a></li>
    </ul>
