我想展示这款可折叠手风琴的第一个元素。我在互联网上做了一些研究，但徒劳无功

Answer 1

我认为你没有掌握手风琴所需的所有HTML，除非你没有将它粘贴在上面。

Bootstrap docs第一个示例将第一个元素设置为打开：

http://twitter.github.com/bootstrap/javascript.html#collapse（这些文档适用于v2.3.2，不再受到官方支持。）

我认为它是“in”中的一个类，它最初是开放的。

<div class="accordion" id="accordion2">
<div class="accordion-group">
<div class="accordion-heading">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseOne">
Collapsible Group Item #1
</a>
</div>
<div id="collapseOne" class="accordion-body collapse in">
<div class="accordion-inner">
Anim pariatur cliche...
</div>
</div>
</div>
<div class="accordion-group">
<div class="accordion-heading">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseTwo">
Collapsible Group Item #2
</a>
</div>
<div id="collapseTwo" class="accordion-body collapse">
<div class="accordion-inner">
Anim pariatur cliche...
</div>
</div>
</div>
</div>

Answer 2

你必须看得太远。

如果您将.in课程改为.collapse，则会保持开放状态：

<div class="accordion-group">  
  <div class="accordion-heading">  
    <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" href="#collapseTwo">  
     Ajout d'un nouveau fonctionnaire
    </a>  
  </div>  
  <div id="collapseTwo" class="accordion-body collapse in"> 
    <div class="accordion-inner">
    </div>  
  </div>  
</div>

Demo (jsfiddle)

<小时/> 你的标记很乱，所以这里是带有正确标记的演示：http://jsfiddle.net/Sherbrow/yYuRz/2/

如果您希望显示style="height: 0px;"元素，则需要从.collapse元素中删除。{/ p>

您还可以触发第一个折叠元素的点击

$("#accordion a:first").trigger("click");

可折叠的bootstrap，显示第一个元素
