更改bootstrap下拉以向右水平放下

Question

我有一个下拉菜单,在它下面打开一排图标(见图1,名称和图片被删除以保持隐私)

我试图让这个菜单打开到选择孩子的右边,而不是在它下面(见图2,我想要得到的东西.图像将打开到下拉的右边而不是下面)

我目前的代码是:

<div class="span4">      
        <div class="btn-group">
  <a class="btn btn-link dropdown-toggle" data-toggle="dropdown" href="#">
  <h3>Choose Child</h3>
  <img id="mainIcons" src="boyStudent.png" alt="boyStudent">
  <span class="caret"></span></a>
  <ul class="dropdown-menu">
    <li>
        <div class="btn-group">
      <a href="parent_homepage_2.html" style="text-align:center;" class="btn btn-link operationsButtons">
       <h5>A</h5>
       <img id="mainIcons" src="boyStudent.png" alt="boyStudent"></a>
       <a href="parent_homepage_2.html" style="text-align:center;" class="btn btn-link operationsButtons">
       <h5>J</h5>
       <img id="mainIcons" src="girlStudent.png" alt="girlStudent"></a>
     </div>
    </li> 
  </ul>

我尝试使用以下示例,这有助于将下拉向左推如何在左侧 打开twitter bootstrap子菜单？ 但我想不出办法将这个用于我想做的事情

谢谢
