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:

The best part is you can do this with any button variant, too:

Trigger dropdown menus above elements by adding .dropup to the parent element.

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

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

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.

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.

Add .dropdown-menu-end to a .dropdown-menu to right align the dropdown menu.

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.

Button dropdowns work with buttons of all sizes, including default and split dropdown buttons.

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

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

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

Make the dropdown menu centered below the toggle with .dropdown-center on the parent element.

By default, the dropdown menu is closed when clicking inside or outside the dropdown menu. You can use the autoClose option to change this behavior of the dropdown.

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.
