Behavior comparison

Dropdown menu vs Tooltip

Choose Dropdown menu for: Grouping secondary actions for one item. Choose Tooltip for: Explaining an unfamiliar icon.

Dimension	Dropdown menuDropdown menu	TooltipTooltip
Trigger	A menu button activated by press, click, Enter, Space, or Arrow Down.	Pointer hover or keyboard focus on the reference element.
Modality	Non-modal action popup that closes after a choice, Escape, or an outside action.	Non-modal supporting description; the page remains active.
Placement	Anchored to the menu button and aligned within the viewport.	Anchored beside its reference and repositioned to remain visible.
Interactivity	A collection of actions with managed keyboard focus, not arbitrary form content.	Contains no interactive controls; focus remains on the reference.
Focus	Opening places menu focus on an enabled item; closing restores focus to the trigger.	Focus remains on the trigger; the tooltip itself never enters the tab order.
Dismissal	Selecting an action, pressing Escape, or safely pressing outside closes the menu.	It closes on Escape and after both focus and pointer leave the trigger and surface.
Accessible role	menu with menuitem children	tooltip
Use case	Grouping secondary actions for one item	Explaining an unfamiliar icon
Mobile behavior	Open on tap, keep generous item targets, and prefer an action sheet for a dense menu.	Never rely on hover alone; expose essential help persistently or through an explicit tap pattern.
