Menu
Menus display a list of choices on temporary surfaces.
Introduction
Joy UI provides three menu-related components:
Menu
: A listbox popup for wrapping the menu items which reuses the styles fromList
.MenuItem
: A menu item which reuses the styles fromListItemButton
.MenuList
: A standalone listbox for composition usage. It also reuses the styles fromList
.
<Menu>
<MenuItem>...</MenuItem>
</Menu>
Playground
Component
After installation, you can start building with this component using the following basic elements:
import Menu from '@mui/joy/Menu';
import MenuItem from '@mui/joy/MenuItem';
export default function MyApp() {
return (
<Menu>
<MenuItem>Add item</MenuItem>
</Menu>
);
}
Basic usage
The basic version of the menu opens over the anchor element by default. You can change this via specific positioning props.
When close to the screen's edge, the menu vertically realigns to make sure that all menu items are completely visible. Choosing an option should immediately, and ideally, commit the option and close the menu.
Size
The menu component comes with three sizes out of the box: sm
, md
(the default), and lg
.
When specifying a size for the Menu
component, menu items inside of it will inherit the value.
Selected
Use the selected
prop to signal whether a MenuItem
is selected or not.
The menu item uses the same styles as the ListItemButton
.
Positioned menu
The Menu
is based on the PopperUnstyled
component, which exposes a few placement props. For example, this is how you'd go for displaying the menu on the bottom-end of the anchor button.
MenuList
composition
To get full control of the DOM structure, use the MenuList
component. You can use it to compose any popup-alike component. The primary responsibility of this component is handling the focus state.
Or display the menu without a popup:

Debugging
To keep the list box open for inspecting elements, enable the Emulate a focused page
option from the Chrome DevTool Rendering tab. You can also access this option by using command menu and search for it.
Common examples
Menu bar
This example replicates the application menu bar on macOS. It supports mouse and keyboard navigation between menu items.
- File
- Edit
- Selection
Side navigation icons
This example is quite common in dashboard applications where the side navigation is shrunk into icons, and the menu is triggered by hovering them.
