使用Reflex有条件地添加DOM元素

import React from 'react';
import { ReflexContainer, ReflexSplitter, ReflexElement } from 'react-reflex';

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      showElement: false, // 控制是否显示DOM元素的状态
    };
  }

  render() {
    return (
      <ReflexContainer orientation="vertical">
        <ReflexElement>
          {/* 在此处添加其他DOM元素 */}
        </ReflexElement>
        <ReflexSplitter />
        <ReflexElement>
          {this.state.showElement && (
            <div>
              {/* 添加的DOM元素 */}
            </div>
          )}
        </ReflexElement>
      </ReflexContainer>
    );
  }
}
