<div class="accordion">
  <div class="accordion-item">
    <div class="accordion-header">选项1</div>
    <div class="accordion-content">内容1</div>
  </div>
  <div class="accordion-item">
    <div class="accordion-header">选项2</div>
    <div class="accordion-content">内容2</div>
  </div>
  <div class="accordion-item">
    <div class="accordion-header">选项3</div>
    <div class="accordion-content">内容3</div>
  </div>
</div>

.accordion-item {
  border: 1px solid #ccc;
  margin-bottom: 10px;
}

.accordion-header {
  background-color: #f0f0f0;
  padding: 10px;
  cursor: pointer;
}

.accordion-content {
  display: none;
  padding: 10px;
}

// 获取所有手风琴选项
var accordionItems = document.querySelectorAll('.accordion-item');

// 给每个选项添加点击事件监听器
accordionItems.forEach(function(item) {
  var header = item.querySelector('.accordion-header');
  var content = item.querySelector('.accordion-content');

  header.addEventListener('click', function() {
    // 切换选项的状态
    if (content.style.display === 'none') {
      content.style.display = 'block';
    } else {
      content.style.display = 'none';
    }
  });
});
