Question

我手风琴有四个标签。我想阻止第一个标签崩溃。如果单击任何其他选项卡，则除第一个选项卡外，所有其他选项卡必须使用默认切换折叠行为。我希望第一个选项卡无法切换并始终打开。

请参阅fiddle

您只需按以下方式更改为第一个手风琴元素 -

<div class="panel panel-default">
    <div class="panel-heading" role="tab" id="headingOne">
      <h4 class="panel-title">
        <a role="button" data-parent="#accordion" href="javascript:void(0)" aria-expanded="true" aria-controls="collapseOne">
          Collapsible Group Item #1
        </a>
      </h4>
    </div>
    <div id="collapseOne" class="panel-collapse" role="tabpanel" aria-labelledby="headingOne">
      <div class="panel-body">

    </div>
  </div>

Bootstrap始终保持手风琴的第一个标签打开
