我正在尝试使用Bootstrap崩溃类。我有两个问题。第一个是我最初点击我的折叠按钮时,需要再次点击才能折叠div。其次,当它崩溃时,div中包含的文本仍然可见。我可以告诉崩溃正在做某事,因为我在外部div附近添加了一个边框。
JSFiddle演示了这个问题:https://jsfiddle.net/sw52dytm/3/
<div style="border: 3px solid #A9A9A9">
<button data-toggle="collapse"
data-target="#Info_Collapse"
class="btn btn-link collapsed">collapse</button>
<h2>Info</h2>
<div class="accordion-body collapse show" id="Info_Collapse">
<span>test</span>
</div>
</div>
答案 0 :(得分:1)
试试这个代码段。我已经改变了一些课程
h2 {
margin: 0;
display: inline-block;
}

通过展开内容加载
更改日志:aria-expanded="true"
并将show class添加到
<div class="collapse show" id="collapseExample">
h2 {
margin: 0;
display: inline-block;
}

<h2>Info</h2>
<button class="btn btn-link collapsed" type="button" data-toggle="collapse" data-target="#collapseExample" aria-expanded="true" aria-controls="collapseExample">
