显然,这种特殊的组合(面包屑内的下拉菜单)不是很好地支持：
我的标记(Bootstrap 2.1.0)：
<ul class="breadcrumb">
<li class="dropdown open">
<a class="dropdown-toggle" id="branches" role="button" data-toggle="dropdown" href="#">default <b class="caret"></b></a>
<ul id="branches-dropdown" class="dropdown-menu">
<li><a tabindex="-1" href="...8109a3a986c7">commissions - <code>8109a3a986c7</code></a></li>
<li><a tabindex="-1" href="...76d3a7022f9e">dashboard-integration - <code>76d3a7022f9e</code></a></li>
<li><a tabindex="-1" href="...4ee00eb42b72">default - <code>4ee00eb42b72</code></a></li>
<li><a tabindex="-1" href="...10755b086192">led-support - <code>10755b086192</code></a></li>
<li><a tabindex="-1" href="...298fa9e18508">stable - <code>298fa9e18508</code></a></li>
<li><a tabindex="-1" href="...990826c5d5df">xdm-customer-selection - <code>990826c5d5df</code></a></li>
</ul>
<span class="divider">/</span>
</li>
<li>
<a href="...4ee00eb42b72">aeroclub.aeroexpress</a> <span class="divider">/</span>
</li>
</ul>
我在这里做错了吗？
