我在 wordpress 中使用 bootstrap 主题并使用 bootstrap 中的手风琴菜单。它在所有其他浏览器中工作正常，但在 IE 8 中它不起作用，并且所有数据都被一个菜单重叠到另一个菜单。
这是手风琴菜单的代码：
<div id="accordion2" class="accordion">
<div class="accordion-group">

这是 bootstrap 中手风琴的 CSS：
.accordion {
margin-bottom: 20px;
}
.accordion-group {
margin-bottom: 2px;
/*border: 1px solid #e5e5e5;
-webkit-border-radius: 4px;
-moz-border-radius: 4px;
border-radius: 4px;*/
}
.accordion-heading {
border-bottom: 0;
background-color:#cccccc;
}
.accordion-heading .accordion-toggle {
display: block;
padding: 2px 4px;
text-decoration:none;
/*background-color:#e52b27;*/
}
.accordion-toggle {
cursor: pointer;
color:#5e5e5e;
text-decoration:none;
}
.accordion-inner {
padding: 2px 4px;
border-top: 1px solid #e5e5e5;
text-decoration:none;
}
