## Features
- Follows the [WAI ARIA Menu](https://www.w3.org/WAI/ARIA/apg/patterns/menu/) design pattern.
- Triggers with a long-press on touch devices.
- Supports modal and non-modal modes.
- Supports submenus.
- Supports items, labels, groups of items.
- Supports checkable items (single or multiple) with optional indeterminate state.
- Support disabled items.
- Complex item labeling support for accessibility.
- Keyboard opening and navigation support.
- Automatic scrolling support during keyboard navigation.
- Typeahead to allow focusing items by typing text.
- Optionally render a pointing arrow.
- Focus is fully managed.
## Anatomy
The context menu consists of:
- **ContextMenu:** The root container for a context menu.
- **ContextMenu.Trigger:** The button that toggles the menu.
- **ContextMenu.Icon:** A small icon that can be displayed inside the menu trigger as a visual affordance for the fact it can be open.
- **ContextMenu.Portal:** Portals its children into the `body` when the menu is open.
- **ContextMenu.Content:** Contains the content to be rendered when the menu is open.
- **ContextMenu.Arrow:** An optional arrow element to render alongside the menu content.
- **ContextMenu.Separator:** Used to visually separate items in the menu.
- **ContextMenu.Group:** Used to group multiple items. Use in conjunction with `ContextMenu.GroupLabel` to ensure good accessibility via automatic labelling.
- **ContextMenu.GroupLabel:** Used to render the label of a group. It won't be focusable using arrow keys.
- **ContextMenu.Sub:** Contains all the parts of a submenu.
- **ContextMenu.SubTrigger:** An item that opens a submenu. Must be rendered inside `ContextMenu.Sub`.
- **ContextMenu.SubContent:** The component that pops out when a submenu is open. Must be rendered inside `ContextMenu.Sub`.
The menu item consists of:
- **ContextMenu.Item:** An item of the select.
- **ContextMenu.ItemLabel:** An accessible label to be announced for the item.
- **ContextMenu.ItemDescription:** An optional accessible description to be announced for the item.
- **ContextMenu.ItemIndicator:** The visual indicator rendered when the item is checked.
The checkable menu item consists of:
- **ContextMenu.RadioGroup:** Used to group multiple `ContextMenu.RadioItem`s and manage the selection.
- **ContextMenu.RadioItem:** An item that can be controlled and rendered like a radio.
- **ContextMenu.CheckboxItem:** An item that can be controlled and rendered like a checkbox.

Copytsx
import { ContextMenu } from "@kobalte/core/context-menu";

import { CheckIcon, ChevronRightIcon, DotFilledIcon } from "some-icon-library";

## Usage
### Origin-aware animations
We expose a CSS custom property `--kb-popper-content-transform-origin` which can be used to animate the content from its computed origin.
```
Copycss
/* style.css */
.context-menu__content,
.context-menu__sub-content {
transform-origin: var(--kb-menu-content-transform-origin);
animation: contentHide 250ms ease-in forwards;
}
.context-menu__content[data-expanded],
.context-menu__sub-content[data-expanded] {
animation: contentShow 250ms ease-out;
}
@keyframes contentShow {
from {
opacity: 0;
transform: scale(0.96);
}
to {
opacity: 1;
transform: scale(1);
}
}
@keyframes contentHide {
from {
opacity: 1;
transform: scale(1);
}
to {
opacity: 0;
transform: scale(0.96);
}
}
```
```
Copycss
/* style.css */
.context-menu__content,
.context-menu__sub-content {
transform-origin: var(--kb-menu-content-transform-origin);
animation: contentHide 250ms ease-in forwards;
}
.context-menu__content[data-expanded],
.context-menu__sub-content[data-expanded] {
animation: contentShow 250ms ease-out;
}
@keyframes contentShow {
from {
opacity: 0;
transform: scale(0.96);
}
to {
opacity: 1;
transform: scale(1);
}
}
@keyframes contentHide {
from {
opacity: 1;
transform: scale(1);
}
to {
opacity: 0;
transform: scale(0.96);
}
}
```
## API Reference
### ContextMenu
`ContextMenu` is equivalent to the `Root` import from `@kobalte/core/context-menu` (and deprecated `ContextMenu.Root`).
| Prop | Description |
| --- | --- |
| onOpenChange | `(open: boolean) => void`
Event handler called when the open state of the menu changes. |
| id | `string`
A unique identifier for the component. The id is used to generate id attributes for nested components. If no id prop is provided, a generated id will be used. |
| modal | `boolean`
Whether the menu should be the only visible content for screen readers, when set to `true`:
\- interaction with outside elements will be disabled.
\- scroll will be locked.
\- focus will be locked inside the menu content.
\- elements outside the menu content will not be visible for screen readers. |
| preventScroll | `boolean`
Whether the scroll should be locked even if the menu is not modal. |
| forceMount | `boolean`
Used to force mounting the menu (portal and content) when more control is needed. Useful when controlling animation with SolidJS animation libraries. |
`ContextMenu` also accepts the following props to customize the placement of the `ContextMenu.Content`.
| Prop | Description |
| --- | --- |
| placement | `Placement`
The placement of the menu content. |
| gutter | `number`
The distance between the menu content and the trigger element. By default, it's 0 plus half of the arrow offset, if it exists. |
| shift | `number`
The skidding of the menu content along the trigger element. |
| flip | `boolean | string`
Controls the behavior of the menu content when it overflows the viewport:
\- If a `boolean`, specifies whether the menu content should flip to the opposite side when it overflows.
\- If a `string`, indicates the preferred fallback placements when it overflows.
The placements must be spaced-delimited, e.g. "top left". |
| slide | `boolean`
Whether the menu content should slide when it overflows. |
| overlap | `boolean`
Whether the menu content can overlap the trigger element when it overflows. |
| sameWidth | `boolean`
Whether the menu content should have the same width as the trigger element. This will be exposed to CSS as `--kb-popper-anchor-width`. |
| fitViewport | `boolean`
Whether the menu content should fit the viewport. If this is set to true, the menu content will have `maxWidth` and `maxHeight` set to the viewport size. This will be exposed to CSS as `--kb-popper-available-width` and `--kb-popper-available-height`. |
| hideWhenDetached | `boolean`
Whether to hide the menu content when the trigger element becomes occluded. |
| detachedPadding | `number`
The minimum padding in order to consider the trigger element occluded. |
| arrowPadding | `number`
The minimum padding between the arrow and the menu content corner. |
| overflowPadding | `number`
The minimum padding between the menu content and the viewport edge. This will be exposed to CSS as `--kb-popper-overflow-padding`. |
