  <Menu>
    <Menu.Item key="1">1st menu item</Menu.Item>
    <Menu.Item key="2">2nd menu item</Menu.Item>
    <Menu.Item key="3">3rd menu item</Menu.Item>
  </Menu>
);

ReactDOM.render(
  <Dropdown overlay={menu} trigger={['contextMenu']}>
    <span style={{ userSelect: 'none' }}>Right Click on Me</span>
  </Dropdown>
, mountNode);
