Dropdowns are toggleable, contextual overlays for displaying lists of links and more. They're made interactive with the included Bootstrap dropdown JavaScript plugin. They're toggled by clicking, not by hovering; this is an intentional design decision. Dropdowns are built on a third party library, Popper.js, which provides dynamic positioning and viewport detection.

Responsive alignment

If you want to use responsive alignment, disable dynamic positioning by adding the data-display="static" attribute and use the responsive variation classes. To align left/right the dropdown menu with the given breakpoint or larger, add .dropdown-menu{-sm|-md|-lg|-xl}-right or .dropdown-menu{-sm|-md|-lg|-xl}-left
Left-aligned but right aligned when large screen
