Dropdowns
Bootstrap provides Dropdowns as a plugin for displaying lists of links. The dropdown is a button which toggles displaying a list of links.
Bootstrap’s dropdowns are designed to be generic and applicable to a variety of situations. For instance, it is possible to create dropdowns that contain search fields or login forms.
Example
<div class="dropdown">
<button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown example
</button>
<div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</div>
Example Explained
The .dropdown class indicates a dropdown menu.
To open the dropdown menu, use a button or a link with a class of .dropdown-toggle and the data-toggle="dropdown attribute.
The .caret class creates a caret arrow icon (▼), which indicates that the button is a dropdown.
Add the .dropdown-menu class to a unordered list element to actually build the dropdown menu.
