Menus
Menus display a list of choices on temporary surfaces.
A Menu displays a list of choices on a temporary surface. They appear when users interact with a button, action, or other control.
Simple Menu
Simple menus open over the anchor element by default (this option can be changed via props). When close to a screen edge, simple menus vertically realign to make all menu items are completely visible.
Choosing an option should immediately ideally commit the option and close the menu.
Disambiguation: In contrast to simple menus, simple dialogs can present additional detail related to the options available for a list item or provide navigational or orthogonal actions related to the primary task. Although they can display the same content, simple menus are preferred over simple dialogs because simple menus are less disruptive to the user’s current context.
Selected menus
If used for item selection, when opened, simple menus attempt to vertically align the currently selected menu item with the anchor element. The currently selected menu item is set using the selected prop.
If text in a simple menu wraps to a second line, use a simple dialog instead. Simple dialogs can have rows with varying heights.
Max height menus
If the height of a menu prevents all menu items from being displayed, the menu can scroll internally.
MenuList composition
The Menu component uses the Popover component internally.
However, you might want to use a different positioning strategy, or not blocking the scroll.
For answering those needs, we expose a MenuList component that you can compose, with Popper in this example.
The primary responsibility of the MenuList component is to handle the focus.
Customized MenuItem
The MenuItem is a wrapper around ListItem with some additional styles.
You can use the same list composition features with the MenuItem component:
