Toggle contextual overlays for displaying lists of links and more with the Bootstrap dropdown plugin.
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
<button> elements to better fit your potential needs.
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.
We use this extra class to reduce the horizontal
padding on either side of the caret by 25% and remove the
margin-left that’s added for regular button dropdowns. Those extra changes keep the caret centered in the split button and provide a more appropriately sized hit area next to the main button.
Trigger dropdown menus above elements by adding
.dropup to the parent element.
Trigger dropdown menus at the right of the elements by adding
.dropright to the parent element.
Trigger dropdown menus at the left of the elements by adding
.dropleft to the parent element.
Active Menu Item
.active to items in the dropdown to style them as active.
Disabled Menu Item
.disabled to items in the dropdown to style them as disabled.
Add a header to label sections of actions in any dropdown menu.
Separate groups of related menu items with a divider.
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.
