【问题描述】：

我正在开发一个AngularJS 应用程序，我使用Bootstrap 3 来设置我的导航样式 (Navbar)，这非常有效。

我的标题

<div class="navbar-header">
    <button class="pull-right visible-xs" ui-toggle-class="show" data-target=".navbar-settings">
       <i class="glyphicon glyphicon-cog"></i></button>

     <a class="navbar-brand text-lt" href="#/dashboard">
       <img class="m-mid" ng-src="{{ logo }}" alt="{{ user.organization.name }}">
       <span class="hidden-folded m-l-xs hide">{{app.name}}</span>
     </a>
 </div>

 <div class="collapse navbar-collapse navbar-settings navbar-right">
     <ul class="nav navbar-nav">
         <li class="dropdown" dropdown>
             <a href class="dropdown-toggle" dropdown-toggle>
                 {{lang.name}} <b class="caret"></b>
              </a>

              <ul class="dropdown-menu">
                 <li ng-repeat="lang in langs">
                     <a class="p-t-sm p-b-sm" ng-click="setLang(lang.key)">
                        {{lang.name}}
                      </a>
                 </li>
               </ul>
           </li>

           <li class="dropdown" dropdown>
              <a href class="dropdown-toggle" dropdown-toggle>
                 <span class="thumb-sm avatar pull-right">
                     <img class="block" ng-src="{{ user.image_path }}" alt="...">
                     <i class="on md b-white bottom"></i>
                  </span>
                  {{name} <b class="caret"></b>
              </a>
              <ul class="dropdown-menu">
                  <li><a href="#/setting"></a></li>
                  <li><a href="#/profile"></a></li>
                  <li><a href="#/help"></a></li>
              </ul>
          </li>
     </ul>
</div>

现在，在移动设备上，navbar-header 中的 button 出现并表现得像 toggle，正如使用 Bootstraps 导航所预期的那样。这意味着用户必须单击它才能打开它，然后在想要关闭它时再次单击它。

在平板电脑/台式机上是两个下拉菜单（来自navbar-collapse）。我想保持这种状态。

我的问题是：在手机上，有没有办法让按钮表现为下拉而不是切换？所以用户可以点击他想要的任何地方并关闭，而不必点击按钮？

这个例子怎么样？

var app = angular.module('app', ['ui.bootstrap']);

app.controller('menu', function($scope) {
    $scope.logo = 'http://i.stack.imgur.com/P1BHs.png';
    $scope.user = {};
    $scope.user.organization = {};
    $scope.user.organization.name = "Org test";
    $scope.user.image_path = "http://ionicframework.com/img/docs/venkman.jpg";
    $scope.app = {name: "App test"};
    $scope.lang = {name: "English"};
    $scope.langs = [{key: "EN", name: "English"},{key: "IT", name: "Italian"}];
    $scope.name = "user123";
    $scope.setLang = function(key) {
      
    }
    
    $scope.containerClick = function($event) {
      console.log("containerClick: "+$scope.navCollapsed)
      $scope.navCollapsed = true;
    }

});

这正是我过去几天一直在寻找的。我唯一需要改变的是删除“ui-toggle-class”和“data-target”。不知何故，它没有停止工作，可能是因为我目前没有使用最新版本的 Angular Bootstrap。无论如何，它现在可以工作了，你已经为我节省了很多冗余代码。非常感谢！！！
