import React, { useState } from 'react';

const App = () => {
  const [isDrawerOpen, setIsDrawerOpen] = useState(false);
  const [selectedTab, setSelectedTab] = useState('home');

  const handleDrawerToggle = () => {
    setIsDrawerOpen(!isDrawerOpen);
  };

  const handleTabChange = (tab) => {
    setSelectedTab(tab);
  };

  return (
    <div>
      <button onClick={handleDrawerToggle}>Toggle Drawer</button>
      {isDrawerOpen && (
        <div>
          {/* Drawer menu content */}
          <ul>
            <li>Menu Item 1</li>

      )}

      <div>
