Headers
Add a header to label sections of actions in any dropdown menu.
Dividers
Separate groups of related menu items with a divider.
Text
Place any freeform text within a dropdown menu with text and use spacing utilities.
Forms
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.
By default, Custom Dropdowns are disabled. Enable Custom Dropdowns by setting $enable-dropdown-colors to true in Scss. When enabled, change colours using .dropdown-menu-{theme-color}.
Set or remove theme maps by using $dropdown-colors if only certain colours are needed. Remove light and dark to avoid duplicate styles as Bootstrap creates these by default. The same goes for secondary as this is the same as light unless you are using a custom colour.
