Bootstrap 4 Dropdowns


Basic Dropdown

A dropdown menu is a toggleable menu that allows the user to choose one value from a predefined list:

Example

<div class="dropdown">
  <button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown">
    Dropdown button
  </button>
  <div class="dropdown-menu">
    <a class="dropdown-item" href="#">Link 1</a>
    <a class="dropdown-item" href="#">Link 2</a>
    <a class="dropdown-item" href="#">Link 3</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.

Add the .dropdown-menu class to a <div> element to actually build the dropdown menu. Then add the .dropdown-item class to each element (links or buttons) inside the dropdown menu.


Dropdown Divider

The .dropdown-divider class is used to separate links inside the dropdown menu with a thin horizontal border:

Example

<div class="dropdown-divider"></div>

Dropdown Header

The .dropdown-header class is used to add headers inside the dropdown menu:

Example

<div class="dropdown-header">Dropdown header 1</div>

Disable and Active items

Highlight a specific dropdown item with the .active class (adds a blue background color).

To disable an item in the dropdown menu, use the .disabled class (gets a light-grey text color and a "no-parking-sign" icon on hover):

Example

<a class="dropdown-item active" href="#">Active</a>
<a class="dropdown-item disabled" href="#">Disabled</a>

You can also create a "dropright" or "dropleft" menu, by adding the .dropright or .dropleft class to the dropdown element. Note that the caret/arrow is added automatically:

Dropdown Text

The .dropdown-item-text class is used to add plain text to a dropdown item, or used on links for default link styling.

  <a class="dropdown-item" href="#">Link 1</a>
  <a class="dropdown-item" href="#">Link 2</a>
  <a class="dropdown-item-text" href="#">Text Link</a>
  <span class="dropdown-item-text">Just Text</span>
</div>
