Dropdowns are toggleable, contextual overlays for displaying lists of links and more. They’re made interactive with the included dropdown directives.

Single button dropdowns

Any single .btn can be turned into a dropdown toggle with some markup changes. Here’s how you can put them to work with either <button>elements.

Split button dropdowns

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.


By default, a dropdown menu is automatically positioned 100% from the top and along the left side of its parent. Add class .dropdown-menu-right to a dropdownMenu to right align the dropdown menu.


Trigger dropdown menus in any side by adding respective parent classes.

Active and Disabled menu item stats

Add .active to items in the dropdown to style them as active or add .disabled to items in the dropdown to style them as disabled.
