我一直在尝试使用bootstrap实现嵌套的手风琴。到目前为止，我能够拥有充当手风琴的嵌套面板，如此jsfiddle中所示，并在下面重复。 （抱歉代码臃肿。）
<div class="panel-group" id="accordion1">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion1" href="#collapseOne">
Collapsible Group Item #1
</a>
</h4>
</div>
<div id="collapseOne" class="panel-collapse collapse in">
<div class="panel-body">Panel 1</div>
</div>
</div>
<!-- I'd like the content of this group to behave as the panels do. -->
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion1" href="#collapseTwo">
Collapsible Group Item #2
</a>
</h4>
</div>
<div id="collapseTwo" class="panel-collapse collapse">
<div class="panel-body">
<div class="collapse-group" id="#accordion2">
<h2>Heading</h2>
<p><a data-toggle="collapse" data-parent="#accordion2" data-target="#collapseTwoOne">View details 2.1 »</a></p>
<p class="collapse" id="collapseTwoOne">Details 1</p>
<p><a data-toggle="collapse" data-parent="#accordion2" data-target="#collapseTwoTwo">View details 2.2 »</a></p>
<p class="collapse" id="collapseTwoTwo">Details 2</p>
</div>
</div>
</div>
</div>
<!-- This group shows how panels may be nested. But what about a plain div inside a panel? -->
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion3" href="#collapseThree">
Collapsible Group Item #3
</a>
</h4>
</div>
<div id="collapseThree" class="panel-collapse collapse in">
<div class="panel-body">
<div class="panel-group" id="accordion2">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion2" href="#collapseThreeOne">
Collapsible Group Item #3.1
</a>
</h4>
</div>
<div id="collapseThreeOne" class="panel-collapse collapse in">
<div class="panel-body">Panel 3.1</div>
</div>
</div>
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion2" href="#collapseThreeTwo">
Collapsible Group Item #3.2
</a>
</h4>
</div>
<div id="collapseThreeTwo" class="panel-collapse collapse">
<div class="panel-body">Panel 3.2</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
但是，我想要实现的是从上面的代码中获取“可折叠组项目＃2”中的项目也以互斥的方式显示，即如果正在显示一个div，那么另一个将是隐藏（如果不是这样）。
我需要做些什么才能获得理想的效果？

试试这个：
<div class="panel-group" id="accordion1">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion1" href="#collapseOne">Collapsible Group Item #1
</a>
</h4>
</div>
<div id="collapseOne" class="panel-collapse collapse in">
<div class="panel-body">Panel 1</div>
</div>
</div>
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion1" href="#collapseTwo">Collapsible Group Item #2
</a>
</h4>
</div>
<div id="collapseTwo" class="panel-collapse collapse">
<div class="panel-body">
<div class="panel-body">
<h2>Heading</h2>
<div class="panel-group" id="accordion21">
<div class="panel">
