Decision

Do you need a short explanation, interactive contextual content, or an action list?

Dimension	Dropdown menuDropdown menu	PopoverPopover
Trigger	A menu button activated by press, click, Enter, Space, or Arrow Down.	An explicit press or click on a named trigger.
Modality	Non-modal action popup that closes after a choice, Escape, or an outside action.	Usually non-modal; surrounding page content remains operable.
Placement	Anchored to the menu button and aligned within the viewport.	Anchored near the trigger with collision-aware positioning.
Interactivity	A collection of actions with managed keyboard focus, not arbitrary form content.	May contain links or controls; focus moves only when the interaction requires it.
Focus	Opening places menu focus on an enabled item; closing restores focus to the trigger.	Focus either remains on the trigger for simple content or moves predictably to the first meaningful control.
Dismissal	Selecting an action, pressing Escape, or safely pressing outside closes the menu.	Escape, the explicit close control, or a safe outside press closes it and restores focus to the trigger.
Accessible role	menu > menuitem	dialog
Use case	Grouping secondary actions for one item	Showing a compact explanation with a link
Mobile behavior	Open on tap, keep generous item targets, and prefer an action sheet for a dense menu.	Keep the trigger easy to tap and use a larger sheet when the content becomes complex.
