Tree

Use Tree

Tree is a named export of @flood-md/react. Connect the package once, then import what you use.

"use client";

import { FloodRoot, Tree } from "@flood-md/react";
import "@flood-md/react/styles.css";

export function Example() {
  return (
    <FloodRoot>
      <Tree label="Project files" items={[{value:"source",label:"Source",children:[{value:"button",label:"Button.tsx"}]}]} />
    </FloodRoot>
  );
}

Design notes

• Tree uses tree/treeitem/group semantics, logical arrows, Home/End and typeahead. Moving focus does not select an item. Enter/Space explicitly selects; multiple selection does not cascade.
• Items have globally unique values. Expansion uses expandedValues/defaultExpandedValues/onExpandedValuesChange; selection uses value/defaultValue/onValueChange. Controlled refusal preserves the host state.
• Read-only allows browsing without selecting. Disabled items remain discoverable but cannot select or expand. hasChildren/loading represent host-owned deferred branches; no fetching or virtualization is built in.
• Application selection writes no form values. Use NavigationTree for ordinary native links. Introduced in 0.2.7.
