Menu is a collection of React components that combine to render
ARIA-compliant [menu](https://www.w3.org/WAI/ARIA/apg/patterns/menu/) and
[menu button](https://www.w3.org/WAI/ARIA/apg/patterns/menubutton/) patterns.
`Menu` itself is a wrapper component and context provider.
It is responsible for managing the state of the menu and its items, and for
rendering the `Menu.TriggerButton` (or the `Menu.SubmenuTriggerItem`)
component, and the `Menu.Popover` component.
## Props
### `as`
- Type: `"symbol" | "object" | "a" | "abbr" | "address" | "area" | "article" | "aside" | "audio" | "b" | "base" | "bdi" | "bdo" | "big" | "blockquote" | "body" | "br" | "button" | "canvas" | ... 516 more ... | ("view" & FunctionComponent<...>)`
- Required: No
The HTML element or React component to render the component as.
### `children`
- Type: `ReactNode`
- Required: No
The elements, which should include one instance of the `Menu.TriggerButton`
component and one instance of the `Menu.Popover` component.
### `defaultOpen`
- Type: `boolean`
- Required: No
- Default: `false`
Whether the menu popover and its contents should be visible by default.
Note: this prop will be overridden by the `open` prop if it is
provided (meaning the component will be used in "controlled" mode).
### `open`
- Type: `boolean`
- Required: No
Whether the menu popover and its contents should be visible.
Should be used in conjunction with `onOpenChange` in order to control
the open state of the menu popover.
Note: this prop will set the component in "controlled" mode, and it will
override the `defaultOpen` prop.
### `onOpenChange`
- Type: `(open: boolean) => void`
- Required: No
A callback that gets called when the `open` state changes.
### `placement`
- Type: `"top" | "bottom" | "left" | "right" | "top-start" | "bottom-start" | "left-start" | "right-start" | "top-end" | "bottom-end" | ...`
- Required: No
- Default: `'bottom-start' for root-level menus, 'right-start' for submenus`
The placement of the menu popover.
## Subcomponents
### Menu.TriggerButton
Renders a menu button that toggles the visibility of a sibling
`Menu.Popover` component when clicked or when using arrow keys.
#### Props
##### `accessibleWhenDisabled`
- Type: `boolean`
- Required: No
Indicates whether the element should be focusable even when it is
`disabled`.
This is important when discoverability is a concern. For example:
> A toolbar in an editor contains a set of special smart paste functions
that are disabled when the clipboard is empty or when the function is not
applicable to the current content of the clipboard. It could be helpful to
keep the disabled buttons focusable if the ability to discover their
functionality is primarily via their presence on the toolbar.
Learn more on [Focusability of disabled
controls](https://www.w3.org/WAI/ARIA/apg/practices/keyboard-interface/#focusabilityofdisabledcontrols).
##### `children`
- Type: `ReactNode`
- Required: No
The contents of the menu trigger button.
##### `disabled`
- Type: `boolean`
- Required: No
- Default: `false`
Determines if the element is disabled. This sets the `aria-disabled`
attribute accordingly, enabling support for all elements, including those
that don't support the native `disabled` attribute.
This feature can be combined with the `accessibleWhenDisabled` prop to
make disabled elements still accessible via keyboard.
##### `render`
- Type: `ReactElement<any, string | JSXElementConstructor<any>> | RenderProp<HTMLAttributes<any> & { ref?: Ref<any>; }>`
- Required: No
Allows the component to be rendered as a different HTML element or React
component. The value can be a React element or a function that takes in the
original component props and gives back a React element with the props
merged.
### Menu.Popover
Renders a dropdown menu element that's controlled by a sibling
`Menu.TriggerButton` component. It renders a popover and automatically
focuses on items when the menu is shown.
The only valid children of `Menu.Popover` are `Menu.Item`,
`Menu.RadioItem`, `Menu.CheckboxItem`, `Menu.Group`, `Menu.Separator`,
and `Menu` (for nested dropdown menus).
#### Props
##### `children`
- Type: `ReactNode`
- Required: No
The contents of the menu popover, which should include instances of the
`Menu.Item`, `Menu.CheckboxItem`, `Menu.RadioItem`, `Menu.Group`, and
`Menu.Separator` components.
##### `gutter`
- Type: `number`
- Required: No
- Default: `8 for root-level menus, 16 for nested menus`
The distance between the popover and the anchor element.
##### `hideOnEscape`
- Type: `BooleanOrCallback<KeyboardEvent | React.KeyboardEvent<Element>>`
- Required: No
- Default: ``( event ) => { event.preventDefault(); return true; }``
Determines if the menu popover will hide when the user presses the
Escape key.
This prop can be either a boolean or a function that accepts an event as an
argument and returns a boolean. The event object represents the keydown
event that initiated the hide action, which could be either a native
keyboard event or a React synthetic event.
##### `modal`
- Type: `boolean`
- Required: No
- Default: `true`
The modality of the menu popover. When set to true, interaction with
outside elements will be disabled and only menu content will be visible to
screen readers.
Determines whether the menu popover is modal. Modal dialogs have distinct
states and behaviors:
- The `portal` and `preventBodyScroll` props are set to `true`. They can
still be manually set to `false`.
- When the dialog is open, element tree outside it will be inert.
##### `shift`
- Type: `number`
- Required: No
- Default: `0 for root-level menus, -8 for nested menus`
The skidding of the popover along the anchor element. Can be set to
negative values to make the popover shift to the opposite side.

- Required: No
