Trigger dropdown menus at the right of the elements by adding .dropend to the parent element.

Add .active to item in the dropdown to style them as active .

Add .disabled to items in the dropdown to style them as disabled .

Add a header to label sections of actions in any dropdown menu.

Opt into darker dropdowns to match a dark navbar or custom style by adding .dropdown-menu-dark onto an existing .dropdown-menu . No changes are required to the dropdown items.

Use data-bs-offset or data-bs-reference to change the location of the dropdown.
