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,
  rootNode: {
    id: 'ROOT',
    name: '',
    children: [
      {
        id: 'node_modules',
        name: 'node_modules',
        children: [
          { id: 'node_modules/zag-js', name: 'zag-js' },
          { id: 'node_modules/pandacss', name: 'panda' },
          {
            id: 'node_modules/@types',
            name: '@types',
            children: [
              { id: 'node_modules/@types/react', name: 'react' },
              { id: 'node_modules/@types/react-dom', name: 'react-dom' },
            ],
          },
        ],
      },
      {
        id: 'src',
        name: 'src',
        children: [
          { id: 'src/app.tsx', name: 'app.tsx' },
          { id: 'src/index.ts', name: 'index.ts' },
        ],
      },
      { id: 'panda.config', name: 'panda.config.ts' },
      { id: 'package.json', name: 'package.json' },
      { id: 'renovate.json', name: 'renovate.json' },
      { id: 'readme.md', name: 'README.md' },
    ],
  },
})

export const Basic = () => {
  return (
    <TreeView.Root collection={collection}>
      <TreeView.Label>Tree</TreeView.Label>
      <TreeView.Tree>
        {collection.rootNode.children?.map((node, index) => (
          <TreeNode key={node.id} node={node} indexPath={[index]} />
        ))}
      </TreeView.Tree>
    </TreeView.Root>
  )
}

const TreeNode = (props: TreeView.NodeProviderProps<Node>) => {
  const { node, indexPath } = props
  return (
    <TreeView.NodeProvider key={node.id} node={node} indexPath={indexPath}>
      {node.children ? (
        <TreeView.Branch>
          <TreeView.BranchControl>
            <TreeView.BranchText>
              <FolderIcon /> {node.name}
            </TreeView.BranchText>
            <TreeView.BranchIndicator>
              <ChevronRightIcon />
            </TreeView.BranchIndicator>
          </TreeView.BranchControl>
          <TreeView.BranchContent>
            <TreeView.BranchIndentGuide />
            {node.children.map((child, index) => (
              <TreeNode key={child.id} node={child} indexPath={[...indexPath, index]} />
            ))}
          </TreeView.BranchContent>
        </TreeView.Branch>
      ) : (
        <TreeView.Item>
          <TreeView.ItemIndicator>
            <CheckSquareIcon />
          </TreeView.ItemIndicator>
          <TreeView.ItemText>
            <FileIcon />
            {node.name}
          </TreeView.ItemText>
        </TreeView.Item>
      )}
    </TreeView.NodeProvider>
  )
}

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.

import { TreeView, createTreeCollection, useTreeView } 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,
  rootNode: {
    id: 'ROOT',
    name: '',
    children: [
      {
        id: 'node_modules',
        name: 'node_modules',
        children: [
          { id: 'node_modules/zag-js', name: 'zag-js' },
          { id: 'node_modules/pandacss', name: 'panda' },
          {
            id: 'node_modules/@types',
            name: '@types',
            children: [
              { id: 'node_modules/@types/react', name: 'react' },
              { id: 'node_modules/@types/react-dom', name: 'react-dom' },
            ],
          },
        ],
      },
      {
        id: 'src',
        name: 'src',
        children: [
          { id: 'src/app.tsx', name: 'app.tsx' },
          { id: 'src/index.ts', name: 'index.ts' },
        ],
      },
      { id: 'panda.config', name: 'panda.config.ts' },
      { id: 'package.json', name: 'package.json' },
      { id: 'renovate.json', name: 'renovate.json' },
      { id: 'readme.md', name: 'README.md' },
    ],
  },
})

export const RootProvider = () => {
  const treeView = useTreeView({ collection })

  return (
    <TreeView.RootProvider value={treeView}>
      <TreeView.Label>Tree</TreeView.Label>
      <TreeView.Tree>
        {collection.rootNode.children?.map((node, index) => (
          <TreeNode key={node.id} node={node} indexPath={[index]} />
        ))}
      </TreeView.Tree>
    </TreeView.RootProvider>
  )
}

const TreeNode = (props: TreeView.NodeProviderProps<Node>) => {
  const { node, indexPath } = props
  return (
    <TreeView.NodeProvider key={node.id} node={node} indexPath={indexPath}>
      {node.children ? (
        <TreeView.Branch>
          <TreeView.BranchControl>
            <TreeView.BranchText>
              <FolderIcon /> {node.name}
            </TreeView.BranchText>
            <TreeView.BranchIndicator>
              <ChevronRightIcon />
            </TreeView.BranchIndicator>
          </TreeView.BranchControl>
          <TreeView.BranchContent>
            <TreeView.BranchIndentGuide />
            {node.children.map((child, index) => (
              <TreeNode key={child.id} node={child} indexPath={[...indexPath, index]} />
            ))}
          </TreeView.BranchContent>
        </TreeView.Branch>
      ) : (
        <TreeView.Item>
          <TreeView.ItemIndicator>
            <CheckSquareIcon />
          </TreeView.ItemIndicator>
          <TreeView.ItemText>
            <FileIcon />
            {node.name}
          </TreeView.ItemText>
        </TreeView.Item>
      )}
    </TreeView.NodeProvider>
  )
}

If you're using the RootProvider component, you don't need to use the Root component.

Keyboard Support

KeyDescription
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.
