  state = { visible: false, childrenDrawer: false };

  showDrawer = () => {
    this.setState({
      visible: true,
    });
  };

  onClose = () => {
    this.setState({
      visible: false,
    });
  };

  showChildrenDrawer = () => {
    this.setState({
      childrenDrawer: true,
    });
  };

  onChildrenDrawerClose = () => {
    this.setState({
      childrenDrawer: false,
    });
  };

  render() {
    return (
      <div>
        <Button type="primary" onClick={this.showDrawer}>
          Open drawer
        </Button>
        <Drawer
