在react原生中创建下拉菜单

import React, { useState } from 'react';

const DropdownMenu = () => {
  const [isOpen, setIsOpen] = useState(false);
  
  const toggleMenu = () => {
    setIsOpen(!isOpen);
  };
  
  return (
    <div>
      <button onClick={toggleMenu}>Toggle Menu</button>
      {isOpen && (
        <ul>
          <li>Option 1</li>
          <li>Option 2</li>
          <li>Option 3</li>
        </ul>
      )}
    </div>
  );
};

export default DropdownMenu;

import React from 'react';
import DropdownMenu from './DropdownMenu';

const App = () => {
  return (
    <div>
      <h1>React Dropdown Menu Example</h1>
      <DropdownMenu />
    </div>
  );
};

export default App;
