Dropdowns
Toggle contextual overlays for displaying lists of links and more with the Bootstrap dropdown plugin.
Examples
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.
And with < a > element:
Menu alignment:
By default, a dropdown menu is automatically positioned 100% from the top and
along the left side of its parent. Add .dropdown-menu-right to a
.dropdown-menu to right align the dropdown menu.
Different colors:
Dropdown split buttons
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.
Dropdown Sizing
Button dropdowns work with buttons of all sizes, including default and split dropdown buttons.
