如何将汉堡包菜单放在文本框中，比如谷歌地图？

<div class="menu-container">
  <input type="checkbox" id="menu-toggle">
  <label for="menu-toggle" class="menu-button">
    <span class="bar"></span>
    <span class="bar"></span>
    <span class="bar"></span>
  </label>
  <ul class="menu">
    <li><a href="#">菜单项1</a></li>
    <li><a href="#">菜单项2</a></li>
    <li><a href="#">菜单项3</a></li>
    <li><a href="#">菜单项4</a></li>
  </ul>
</div>

.menu-container {
  position: relative;
}

.menu-button {
  display: block;
  width: 30px;
  height: 30px;
  cursor: pointer;
}

.bar {
  display: block;
  width: 100%;
  height: 2px;
  background-color: #000;
  margin-bottom: 4px;
}

.menu {
  position: absolute;
  top: 100%;
  left: 0;
  width: 200px;
  background-color: #fff;
  padding: 10px;
  display: none;
}

.menu li {
  margin-bottom: 10px;
}

.menu li a {
  color: #000;
  text-decoration: none;
}

document.getElementById('menu-toggle').addEventListener('change', function() {
  var menu = document.querySelector('.menu');
  menu.style.display = this.checked ? 'block' : 'none';
});
