Dropdowns
Toggle contextual overlays for displaying lists of links and more with the Bootstrap dropdown plugin. Read the Official Bootstrap Documentation for a full list of instructions and other options.
Basic Example
Wrap the dropdown’s toggle (your button or link) and the dropdown menu within .dropdown
, or another element that declares position: relative;. Dropdowns can be triggered from
<a>
or <button>
elements to better fit your potential needs.
Dropdown variations
Add class .btn-*
for solid colored buttons.
Split button
Similarly, create split button dropdowns with virtually the same markup as single button dropdowns, but with the addition of .dropdown-toggle-split
for proper spacing around the dropdown caret.
Sizing
Button dropdowns work with buttons of all sizes, including default and split dropdown buttons.
Dropup
Trigger dropdown menus above elements by adding .dropup
to the parent element.
Dropright
Trigger dropdown menus at the right of the elements by adding .dropright
to the parent element.
Dropleft
Trigger dropdown menus at the right of the elements by adding .dropleft
to the parent element.
Active menu item
Add .active
to items in the dropdown to style them as active.
Disabled menu item
Add .disabled
to items in the dropdown to style them as active.
Dropdown header
Add a header to label sections of actions in any dropdown menu.
Dropdown dividers
Add a header to label sections of actions in any dropdown menu.
Text in dropdown
Place any freeform text within a dropdown menu with text and use spacing utilities. Note that you’ll likely need additional sizing styles to constrain the menu width.
Forms in dropdown
Put a form within a dropdown menu, or make it into a dropdown menu, and use margin or padding utilities to give it the negative space you require.
