    console.log('Trigger Expand');
  };

  render() {
    return (
      <DirectoryTree multiple defaultExpandAll onSelect={this.onSelect} onExpand={this.onExpand}>
        <TreeNode title="parent 0" key="0-0">
          <TreeNode title="leaf 0-0" key="0-0-0" isLeaf />
          <TreeNode title="leaf 0-1" key="0-0-1" isLeaf />
        </TreeNode>
        <TreeNode title="parent 1" key="0-1">
          <TreeNode title="leaf 1-0" key="0-1-0" isLeaf />
          <TreeNode title="leaf 1-1" key="0-1-1" isLeaf />
