Dropdowns are toggleable, contextual overlays for displaying lists of links and more. They’re made interactive with the included Bootstrap dropdown javascript plugin. Read the Official Bootstrap Documentationfor a full list of instructions and other options.
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 link or button elements to better fit your potential needs.
