【问题描述】：

来自Bootstrap 4的官方documentation，有如下代码。如果我打开/显示一张卡片，我应该怎么做才能不折叠其他卡片。我希望最初显示/打开所有卡片，然后用户只需选择他想要折叠/关闭的卡片。

<div id="accordion">
  <div class="card">
    <div class="card-header" id="headingOne">
      <h5 class="mb-0">
        <button class="btn btn-link" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
          Collapsible Group Item #1
        </button>
      </h5>
    </div>

    <div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordion">
      <div class="card-body">

【参考方案1】：

尝试删除data-parent="#accordion"

如果提供了 parent，则所有可折叠的元素在 显示此可折叠项目时，将关闭指定的父级。 （类似于传统的手风琴行为 - 这取决于 卡类）。该属性必须在目标可折叠上设置 地区。
