import { BlockTree, type BaseBlock, type BlockRenderers } from '@dnd-block-tree/react'

interface MyBlock extends BaseBlock {
  type: 'section' | 'task'
  title: string
}

const renderers: BlockRenderers<MyBlock, ['section']> = {
  section: ({ block, children, isExpanded, onToggleExpand }) => (
    <div>
      <button onClick={onToggleExpand}>{isExpanded ? '▼' : '▶'} {block.title}</button>
      {isExpanded && <div className="ml-4">{children}</div>}
    </div>
  ),
  task: ({ block }) => <div>{block.title}</div>,
}

function App() {
  const [blocks, setBlocks] = useState<MyBlock[]>(initialBlocks)
  return (
    <BlockTree
