请告诉我为什么下拉菜单不起作用，搜索框内也没有显示 fa fa-search 图标。
下拉菜单没有折叠。和来自 http://fortawesome.github.io/Font-Awesome/icon/search/ 的搜索图标没有按应有的方式显示在搜索框中。
非常感谢您的帮助!

最佳答案
对于搜索问题，需要像这样把input-group-addon放在里面
<i class="input-group-addon fa fa-search"></i>
或者最好从 bootstrap 网站上获取
<div class="input-group right-inner-addon pull-right">
<div class="input-group-addon">
<i class="input-group-addon fa fa-search">
</div>
<input type="search" class="form-control" placeholder="search">
</div> <!-- End of Search -->
对于下拉列表，我不确定，但我的猜测是你需要 li 中的下拉类吗 代替 你能试一下吗
