bootstrap v3.3.7 如何显示打开的多个手风琴？

Question

我正在使用 Bootstrap v3.3.7。我正在展示正在工作的手风琴。当页面加载时，第一个手风琴将打开。现在，当我点击第二个时，前一个手风琴就关闭了，我不想要。我需要当用户点击打开的手风琴时关闭。总之，我要显示多个手风琴打开。

这是我在代码中使用的示例 https://getbootstrap.com/docs/3.3/javascript/#collapse-example-accordion

在这里，第一个手风琴是打开的，如果你点击第二个，它会关闭前一个打开的手风琴。

我需要，在页面加载时第一个手风琴打开，如果点击第二个打开第二个手风琴，但我不想关闭前一个。

我正在使用以下代码。你能帮我解决这个问题吗？

Answer 1

这很简单，只需将 div 中的 class='collapse' 更改为 class='collapse in' 并使用 class of panel-collapse

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>

<div class="panel-group" id="accordion" role="tablist" aria-multiselectable="false">
  <div class="panel panel-default">
    <div class="panel-heading" role="tab" id="headingOne">
      <h4 class="panel-title">
        <a role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
          Collapsible Group Item #1
        </a>
      </h4>
    </div>
    <div id="collapseOne" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="headingOne">
      <div class="panel-body">
        Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia
      </div>
    </div>
  </div>
  <div class="panel panel-default">
    <div class="panel-heading" role="tab" id="headingTwo">
      <h4 class="panel-title">
        <a class="collapsed" role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseTwo" aria-expanded="false" aria-controls="collapseTwo">
          Collapsible Group Item #2
        </a>
      </h4>
    </div>
    <div id="collapseTwo" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="headingTwo">
      <div class="panel-body">
        Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia

      </div>
    </div>
  </div>
  <div class="panel panel-default">
    <div class="panel-heading" role="tab" id="headingThree">
      <h4 class="panel-title">
        <a class="collapsed" role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseThree" aria-expanded="false" aria-controls="collapseThree">
          Collapsible Group Item #3
        </a>
      </h4>
    </div>
    <div id="collapseThree" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="headingThree">

只需删除 data-parent="#accordion"

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

<div class="panel-group" id="accordion" role="tablist" aria-multiselectable="false">

        <a role="button" data-toggle="collapse" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
          Collapsible Group Item #1
        </a>
      </h4>
    </div>
    <div id="collapseOne" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="headingOne">
      <div class="panel-body">
        Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia
      </div>
    </div>
  </div>

  <div class="panel panel-default">
    <div class="panel-heading" role="tab" id="headingTwo">

      </h4>
    </div>
    <div id="collapseTwo" class="panel-collapse collapse" role="tabpanel" aria-labelledby="headingTwo">
      <div class="panel-body">
        Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia

      </div>
    </div>
  </div>

  <div class="panel panel-default">
    <div class="panel-heading" role="tab" id="headingThree">
      <h4 class="panel-title">
        <a class="collapsed" role="button" data-toggle="collapse" href="#collapseThree" aria-expanded="false" aria-controls="collapseThree">

When you don't want any panel to get affected by other panel don't add data-parent and it will work as you require. check the docs here
