How to use the rax.PropTypes.any function in rax

// show placeholder only for non root nodes
        shouldShowPlaceholder={depth > 0}
        // Render a node from name and data (or possibly other props like isNonenumerable)
        nodeRenderer={nodeRenderer}
        {...this.props}
      >
        {// only render if the node is expanded
          expanded ? this.renderChildNodes(data, path) : undefined}
      
    );
  }
