Question

我对引导程序提供的导航栏有疑问。使用下拉菜单时，它将生成上下箭头。我如何删除箭头？我已经搜索了互联网，但仍然无法解决问题。

 <nav class="navbar navbar-default">
     <div class="container-fluid">

        <div class="navbar-header">
     <button type="button" id="sidebarCollapse" class="btn btn-info navbar-btn">
        <i class="glyphicon glyphicon-align-left"></i>
            <span></span>
     </button>
     </div>

       <ul class="nav navbar-nav navbar-right">
           <li class="dropdown">
            <a href="#" class="dropdown-toggle" data-toggle="dropdown" >Menu<span class="caret"></span></a>
               <ul class="dropdown-menu">
                 <li><a href="#">a</a></li>
                 <li><a href="#">b</a></li>
                 <li><a href="#">c</a></li>
               </ul>
           </li>
        </ul>
     </div>
 </nav>

您可以删除<span class="caret"></span>，也可以通过CSS将其隐藏起来，如下所示：

.dropdown-toggle .caret {
        display:none;
    }
