这里的html代码也是

<div class="container-fluid">
  <div class="row">

    <div class="col-xs-12 col-sm-3">

        <div class="panel panel-info">
            <div class="panel-heading">Categories <span class="badge pull-right">12345</span></div>
            <ul id="categories-menu" class="nav nav-pills nav-stacked">
                <li id="cid-1"><a href="automotive-vehicles">Automotive Vehicles</a></li>
                <li id="cid-8"><a href="business-to-business">Business-to-Business</a></li>
                <li id="cid-10"><a href="community">Community</a></li>
                <li id="cid-2"><a href="electronics">Electronics</a></li>
                <li id="cid-11"><a href="events">Events</a></li>

                <li id="cid-13"><a href="freebies">Freebies</a></li>
            </ul>            
        </div>

        <div class="panel panel-primary">
            <div class="panel-heading">Site statistics</div>
            <ul class="list-unstyled">
                <li>1000 Users</li>
                <li>200 Online</li>
                <li>300 Hidden</li>
            </ul>
        </div>

    </div>

    <div class="col-xs-12 col-sm-9">

使用bootstrap折叠类包装你的ul：

<div class="collapse navbar-collapse" id="collapse">  
    <ul id="categories-menu" class="nav nav-pills nav-stacked">
        <li id="cid-1"><a href="automotive-vehicles">Automotive Vehicles</a></li>
        <li id="cid-8"><a href="business-to-business">Business-to-Business</a></li>
        <li id="cid-10"><a href="community">Community</a></li>
        <li id="cid-2"><a href="electronics">Electronics</a></li>
        <li id="cid-11"><a href="events">Events</a></li>
        <li id="cid-12"><a href="fashion">Fashion</a></li>
        <li id="cid-13"><a href="freebies">Freebies</a></li>
    </ul> 
</div>

然后将数据切换和数据目标添加到要切换菜单的元素。例如代码中的徽章12345：

<span data-toggle="collapse" data-target="#collapse" class="badge pull-right">
