`Tree`	`function Tree`	Public function Tree.

Interaction

Up and Down move, Right expands, Left collapses or moves to the parent, and Enter activates.

API and events

Expansion and activation are surfaced through callbacks.

Every interactive component publishes semantic roles, labels, state, and focus identity through the renderer's SemanticRegistry. Callback failures flow to the owning application's error boundary.

Example

import type { ComponentProps } from "react";
import { Tree } from "@/components/tuil/data-display/tree";

export function Example(props: ComponentProps<typeof Tree>) {
  return <Tree {...props} />;
}

Registry-installed components are source-owned: customize the generated file in your application, and use the package reference for the shared runtime contracts.
