手风琴布局／可折叠布局（Accordion / Collapsible）

手风琴布局Accordion Layout

通常，手风琴布局可以这样实现:

<div class="accordion-list">
    <div class="accordion-item">
        <div class="accordion-item-toggle">...</div>
        <div class="accordion-item-content">...</div>
    </div>
    <div class="accordion-item accordion-item-expanded">
        <div class="accordion-item-toggle">...</div>
        <div class="accordion-item-content">...</div>
    </div>
    <div class="accordion-item">
        <div class="accordion-item-toggle">...</div>
        <div class="accordion-item-content">...</div>
    </div>
    ...
</div>

上面的代码:

• accordion-list - 多个手风琴元素的列表. 可选
  • accordion-item - 单个手风琴元素. 必选
    • accordion-item-toggle - 用来展开／折叠手风琴元素内容的开关. 必选
    • accordion-item-content - 隐藏的手风琴元素的内容. 必选
  • accordion-item-expanded - 展开的手风琴元素

折叠布局(Collapsible Layout)

如果你希望独立的可折叠元素，你可以不使用"accordion-list"包裹元素:

    <!-- Single collapsible element -->
    <div class="accordion-item">
        <div class="accordion-item-toggle">...</div>
        <div class="accordion-item-content">...</div>
    </div>
    <!-- Another separate collapsible element -->
    <div class="accordion-item">
        <div class="accordion-item-toggle">...</div>
        <div class="accordion-item-content">...</div>
    </div>

手风琴列表视图（Accordion List View）

如果你希望给列表视图加上手风琴布局，你应该使用"item-link"元素而不是"accordion-toggle"元素:

<div class="list-block accordion-list">
    <ul>
        <li class="accordion-item">
  <a href="" class="item-link item-content">
      <div class="item-inner">
          <div class="item-title">Item 1</div>
      </div>
  </a>
  <div class="accordion-item-content">Item 1 content ...</div>
        </li>
        <li class="accordion-item">
  <a href="" class="item-link item-content">
      <div class="item-inner">
          <div class="item-title">Item 2</div>
      </div>
  </a>
  <div class="accordion-item-content">Item 2 content ...</div>
        </li>
    </ul>
</div>
