Tree View
A component that is used to show a tree hierarchy.
Anatomy
To set up the tree view component correctly, you'll need to understand its anatomy and how we name its parts.
Each part includes a
data-part
attribute to help identify them in the DOM.
Examples
Learn how to use the TreeView
component in your project. Let's take a look at the most basic
example:
import { TreeView, createTreeCollection } from '@ark-ui/react/tree-view'
import { CheckSquareIcon, ChevronRightIcon, FileIcon, FolderIcon } from 'lucide-react'
interface Node {
id: string
name: string
children?: Node[]
}
const collection = createTreeCollection<Node>({
nodeToValue: (node) => node.id,
nodeToString: (node) => node.name,

Using the Root Provider
The RootProvider
component provides a context for the tree-view. It accepts the value of the useTree-view
hook.
You can leverage it to access the component state and methods from outside the tree-view.
If you're using the
RootProvider
component, you don't need to use theRoot
component.

Accessibility
Complies with the Tree View WAI-ARIA design pattern.
Keyboard Support
Key | Description |
---|---|
Tab | Moves focus to the tree view, placing the first tree view item in focus. |
EnterSpace | Selects the item or branch node |
ArrowDown | Moves focus to the next node |
ArrowUp | Moves focus to the previous node |
ArrowRight | When focus is on a closed branch node, opens the branch. When focus is on an open branch node, moves focus to the first item node. |
ArrowLeft | When focus is on an open branch node, closes the node. When focus is on an item or branch node, moves focus to its parent branch node. |
Home | Moves focus to first node without opening or closing a node. |
End | Moves focus to the last node that can be focused without expanding any nodes that are closed. |
a-zA-Z | Focus moves to the next node with a name that starts with the typed character. The search logic ignores nodes that are descendants of closed branch. |
* | Expands all sibling nodes that are at the same depth as the focused node. |
Shift + ArrowDown | Moves focus to and toggles the selection state of the next node. |
Shift + ArrowUp | Moves focus to and toggles the selection state of the previous node. |
Ctrl + A | Selects all nodes in the tree. If all nodes are selected, unselects all nodes. |
