} ``` ## Anatomy Import the components and place them together: ```jsx title="Anatomy" import { ContextMenu } from '@base-ui/react/context-menu'; <ContextMenu.Root> <ContextMenu.Trigger /> <ContextMenu.Portal> <ContextMenu.Backdrop /> <ContextMenu.Positioner> <ContextMenu.Popup> <ContextMenu.Arrow /> <ContextMenu.Item /> <ContextMenu.LinkItem /> <ContextMenu.Separator /> <ContextMenu.SubmenuRoot> <ContextMenu.SubmenuTrigger /> </ContextMenu.SubmenuRoot> <ContextMenu.Group> <ContextMenu.GroupLabel /> </ContextMenu.Group> <ContextMenu.RadioGroup> <ContextMenu.RadioItem> <ContextMenu.RadioItemIndicator /> </ContextMenu.RadioItem> </ContextMenu.RadioGroup> <ContextMenu.CheckboxItem> <ContextMenu.CheckboxItemIndicator /> </ContextMenu.CheckboxItem> </ContextMenu.Popup> </ContextMenu.Positioner> </ContextMenu.Portal> </ContextMenu.Root>; ``` ## Examples [Menu](/react/components/menu.md) displays additional demos, many of which apply to the context menu as well. ### Nested menu To create a submenu, create a `<ContextMenu.SubmenuRoot>` inside the parent context menu. Use the `<ContextMenu.SubmenuTrigger>` part for the menu item that opens the nested menu. ## Demo ### Tailwind This example shows how to implement the component using Tailwind CSS. ```tsx /* index.tsx */ import * as React from 'react';

} ``` ## API reference ### Root A component that creates a context menu activated by right clicking or long pressing. Doesn't render its own HTML element. **Root Props:** | Prop | Type | Default | Description | | :------------------- | :----------------------------------------------------------------------------- | :----------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | defaultOpen | `boolean` | `false` | Whether the menu is initially open. To render a controlled menu, use the `open` prop instead. | | open | `boolean` | - | Whether the menu is currently open. | | onOpenChange | `((open: boolean, eventDetails: ContextMenu.Root.ChangeEventDetails) => void)` | - | Event handler called when the menu is opened or closed. | | highlightItemOnHover | `boolean` | `true` | Whether moving the pointer over items should highlight them.&#xA;Disabling this prop allows CSS `:hover` to be differentiated from the `:focus` (`data-highlighted`) state. | | actionsRef | `React.RefObject<MenuRoot.Actions \| null>` | - | A ref to imperative actions. `unmount`: Manually unmounts the menu.&#xA;Call this after any externally controlled closing animation finishes.`close`: When specified, the menu can be closed imperatively. | | closeParentOnEsc | `boolean` | `false` | When in a submenu, determines whether pressing the Escape key&#xA;closes the entire menu, or only the current child menu. | | defaultTriggerId | `string \| null` | - | ID of the trigger that the popover is associated with.&#xA;This is useful in conjunction with the `defaultOpen` prop to create an initially open popover. | | handle | `MenuHandle<unknown>` | - | A handle to associate the menu with a trigger.&#xA;If specified, allows external triggers to control the menu's open state. | | loopFocus | `boolean` | `true` | Whether to loop keyboard focus back to the first item&#xA;when the end of the list is reached while using the arrow keys. | | onOpenChangeComplete | `((open: boolean) => void)` | - | Event handler called after any animations complete when the menu is closed. | | triggerId | `string \| null` | - | ID of the trigger that the popover is associated with.&#xA;This is useful in conjunction with the `open` prop to create a controlled popover.&#xA;There's no need to specify this prop when the popover is uncontrolled (that is, when the `open` prop is not set). | | disabled | `boolean` | `false` | Whether the component should ignore user interaction. | | orientation | `MenuRoot.Orientation` | `'vertical'` | The visual orientation of the menu.&#xA;Controls whether roving focus uses up/down or left/right arrow keys. | | children | `React.ReactNode \| PayloadChildRenderFunction<unknown>` | - | The content of the popover.&#xA;This can be a regular React node or a render function that receives the `payload` of the active trigger. | ### Root.Props Re-export of [Root](/react/components/context-menu.md) props. ### Root.State ```typescript type ContextMenuRootState = {}; ``` ### Root.Actions ```typescript type ContextMenuRootActions = { unmount: () => void; close: () => void }; ``` ### Root.ChangeEventReason ```typescript type ContextMenuRootChangeEventReason = | 'trigger-hover' | 'trigger-focus' | 'trigger-press' | 'outside-press' | 'focus-out' | 'list-navigation' | 'escape-key' | 'item-press' | 'close-press' | 'sibling-open' | 'cancel-open' | 'imperative-action' | 'none'; ``` ### Root.ChangeEventDetails ```typescript type ContextMenuRootChangeEventDetails = ( | { reason: 'trigger-hover'; event: MouseEvent } | { reason: 'trigger-focus'; event: FocusEvent } | { reason: 'trigger-press'; event: MouseEvent | PointerEvent | TouchEvent | KeyboardEvent } | { reason: 'outside-press'; event: MouseEvent | PointerEvent | TouchEvent } | { reason: 'focus-out'; event: FocusEvent | KeyboardEvent } | { reason: 'list-navigation'; event: KeyboardEvent } | { reason: 'escape-key'; event: KeyboardEvent } | { reason: 'item-press'; event: MouseEvent | PointerEvent | KeyboardEvent } | { reason: 'close-press'; event: MouseEvent | PointerEvent | KeyboardEvent } | { reason: 'sibling-open'; event: Event } | { reason: 'cancel-open'; event: MouseEvent } | { reason: 'imperative-action'; event: Event } | { reason: 'none'; event: Event } ) & { /** Cancels Base UI from handling the event. */ cancel: () => void; /** Allows the event to propagate in cases where Base UI will stop the propagation. */ allowPropagation: () => void; /** Indicates whether the event has been canceled. */ isCanceled: boolean; /** Indicates whether the event is allowed to propagate. */ isPropagationAllowed: boolean; /** The element that triggered the event, if applicable. */ trigger: Element | undefined; }; ``` ### Trigger An area that opens the menu on right click or long press.

Use it to prevent the arrow element from hanging out of the rounded corners of a popup. | | anchor | `Element \| VirtualElement \| React.RefObject<Element \| null> \| (() => Element \| VirtualElement \| null) \| null` | - | An element to position the popup against.&#xA;By default, the popup will be positioned against the trigger. | | collisionAvoidance | `CollisionAvoidance` | - | Determines how to handle collisions when positioning the popup. `side` controls overflow on the preferred placement axis (`top`/`bottom` or `left`/`right`): `'flip'`: keep the requested side when it fits; otherwise try the opposite side&#xA;(`top` and `bottom`, or `left` and `right`).`'shift'`: never change side; keep the requested side and move the popup within&#xA;the clipping boundary so it stays visible.`'none'`: do not correct side-axis overflow. `align` controls overflow on the alignment axis (`start`/`center`/`end`): `'flip'`: keep side, but swap `start` and `end` when the requested alignment overflows.`'shift'`: keep side and requested alignment, then nudge the popup along the&#xA;alignment axis to fit.`'none'`: do not correct alignment-axis overflow. `fallbackAxisSide` controls fallback behavior on the perpendicular axis when the&#xA;preferred axis cannot fit: `'start'`: allow perpendicular fallback and try the logical start side first&#xA;(`top` before `bottom`, or `left` before `right` in LTR).`'end'`: allow perpendicular fallback and try the logical end side first&#xA;(`bottom` before `top`, or `right` before `left` in LTR).`'none'`: do not fallback to the perpendicular axis. When `side` is `'shift'`, explicitly setting `align` only supports `'shift'` or `'none'`.&#xA;If `align` is omitted, it defaults to `'flip'`. | | collisionBoundary |
