我使用带有两个折叠菜单的主题中给出的代码制作了一个导航栏，但是当一个处于事件状态然后打开第二个时，第二个的折叠内容将添加到第一个菜单内容的末尾。打开第二个菜单时如何关闭另一个菜单？
html {
position: relative;
min-height: 100%;
}
body {
margin-bottom: 60px;
}
.footer {
position: absolute;
bottom: 0;
width: 100%;
height: 60px;
line-height: 60px;
/* Vertically center the text there */
background-color: #AD2D2D;

像这样为折叠 show 事件添加处理程序...
$('#links').on('show.bs.collapse', function () {
$('#account').collapse("hide");
})
$('#account').on('show.bs.collapse', function () {
$('#links').collapse("hide");
})
