Tree view

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 } from '@ark-ui/react'

export const Basic = () => {
  return (
    <TreeView.Root>
      <TreeView.Label>Tree</TreeView.Label>
      <TreeView.Tree>
        <TreeView.Item value="1.0">
          <TreeView.ItemText>1.0</TreeView.ItemText>
        </TreeView.Item>
        <TreeView.Branch value="2.0">
          <TreeView.BranchControl>
            <TreeView.BranchIndicator>↕️</TreeView.BranchIndicator>
            <TreeView.BranchText>2.0</TreeView.BranchText>
          </TreeView.BranchControl>
          <TreeView.BranchContent>
            <TreeView.Item value="2.1">
              <TreeView.ItemText>2.2</TreeView.ItemText>
            </TreeView.Item>
            <TreeView.Item value="2.2">
              <TreeView.ItemText>2.2</TreeView.ItemText>
            </TreeView.Item>
          </TreeView.BranchContent>
        </TreeView.Branch>
      </TreeView.Tree>
    </TreeView.Root>
  )
}

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.
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.

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.
