Javascript 单击切换按钮时引导导航栏项目对齐

在小屏幕中，当我单击切换按钮时，我的导航栏项目显示在搜索栏下方，如下所示。我想把通知铃和欢迎用户元素对齐，就在about-like-home和about下面

这是我的html代码

<nav class="navbar navbar-default navbar-fixed-top" role="navigation">
      <div class="container-fluid">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">

                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>
                  <div  class="navbar-brand">

您只需在引导程序上使用“隐藏的xs”类和“可见的xs”类即可

首先，添加“隐藏X”以在移动屏幕上隐藏它们

<ul class="nav pull-right hidden-xs"> 
                <li class="dropdown">

                  <a href="#" class="dropdown-toggle" data-toggle="dropdown">
                  <span class="glyphicon glyphicon-user">
                  </span>Welcome, User <b class="caret"></b>
                  </a>
                    <ul class="dropdown-menu">
                        <li><a href="/user/preferences"><i class="icon-cog"></i> Preferences</a></li>
                        <li><a href="/help/support"><i class="icon-envelope"></i> Contact Support</a></li>
                        <li class="divider"></li>
                        <li><a href="/auth/logout"><i class="icon-off"></i> Logout</a></li>
                    </ul>
                </li>
            </ul>

第二，在Home链接之前复制上面的代码，并添加“visible xs”类，告诉浏览器这只显示在手机屏幕上

<li class="dropdown visible-xs">

                  <a href="#" class="dropdown-toggle" data-toggle="dropdown">
                  <span class="glyphicon glyphicon-user">
                  </span>Welcome, User <b class="caret"></b>
                  </a>
                    <ul class="dropdown-menu">
                        <li><a href="/user/preferences"><i class="icon-cog"></i> Preferences</a></li>
                        <li><a href="/help/support"><i class="icon-envelope"></i> Contact Support</a></li>
                        <li class="divider"></li>
                        <li><a href="/auth/logout"><i class="icon-off"></i> Logout</a></li>
                    </ul>
                </li>

                  <a href="#" class="dropdown-toggle" data-toggle="dropdown">

                  </span>Welcome, User <b class="caret"></b>
                  </a>
                    <ul class="dropdown-menu">

                        <li><a href="/help/support"><i class="icon-envelope"></i> Contact Support</a></li>
                        <li class="divider"></li>
