我已经创建了一个下拉菜单，它工作正常，但打开其他时不能关闭。我需要关闭一个时，其他打开。它应该通过CSS只，没有JS。所以，我需要一个修复，使所有的独立工作。我已经尝试过，但不能做到这一点。我张贴的HTML和CSS代码下面请看。请帮助我修复它。

对于第二个下拉列表，你需要改变类名。你的第一个下拉列表和第二个下拉列表有完全相同的类名，这将做什么是你点击第二个下拉列表，但你激活第一。也给予CSS的每一个新的类名，你做。

要使两个下拉列表独立，您需要确保它们具有唯一的标识符。

.dropdown {
  position: relative;
  display: inline-block;
}

.dropbtn {
  background-color: #4CAF50;
  color: white;
  padding: 16px;
  font-size: 16px;
  border: none;
  cursor: pointer;
}

.dropdown-content {
  display: none;
  position: absolute;
  z-index: 1;
}

.dropdown-content a {
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
}

.dropdown:hover .dropdown-content {
  display: block;
}
<div class="dropdown">
  <button class="dropbtn">Dropdown 1</button>
  <div class="dropdown-content">
    <a href="#">Link 1</a>
    <a href="#">Link 2</a>
    <a href="#">Link 3</a>
  </div>
</div>

<div class="dropdown">
  <button class="dropbtn">Dropdown 2</button>
  <div class="dropdown-content">
    <a href="#">Link 4</a>
    <a href="#">Link 5</a>
    <a href="#">Link 6</a>
  </div>
</div>

在这段代码中，您可以看到每个下拉列表都有一个唯一的父容器，类为'dropdown'，并且每个下拉列表都有自己唯一的类'dropdown'。' dropdown-content 'div包含下拉列表的内容。
