## Dropdowns
|
||
|
||
Bootstrap provides Dropdowns as a plugin for displaying lists of links.
|
||
A 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
|
||
|
||
```html
|
||
<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.
