javascript - Bootstrap 4.1 - 右对齐下拉插入符号

问题描述

我在 Bootstrap 4.1 中工作，我有一个导航栏，它启动一个带有选项卡的模态对话框和一个带有图像图标的下拉菜单。我希望下拉菜单的“插入符号”或向下箭头出现在图像的右侧。

我为该类创建了一个自定义类dropdown-toggle，并尝试了该类的各种设置，但似乎没有任何效果。这是自定义类：

 .dropdown-toggle { align-content: center; }

这是我在 JSFiddle 上的完整代码：https ://jsfiddle.net/tsmolskow/aq9Laaew/254602/

这是代码的模态对话框部分：

      <div tabindex="-1" class="modal fade" id="MyNNSModal" role="dialog" aria-hidden="true" aria-labelledby="exampleModalLabel">
         <div class="modal-dialog modal-lg" role="document">
            <div class="modal-content">
               <div class="modal-header">
                  <div class="tabbable">

                     <!-- Nav Tabs, Modal Nav Bar -->

                           <ul class="nav nav-tabs" role="tablist">
                              <li class="nav-item active">
                                 <a class="nav-link active" href="#aDepartments" data-toggle="tab">Departments</a></li>
                              <li class="nav-item active">
                                 <a class="nav-link" href="#aResources" data-toggle="tab">Resources</a></li>
                              <li class="nav-item active">
                                 <a class="nav-link" href="#aProcedures" data-toggle="tab">Procedures</a></li>
                              <li class="nav-item active">
                                 <a class="nav-link" href="#aNews" data-toggle="tab">News</a></li>                              
                                              
                          </ul> 

                  </div>
                    <div class="d-flex align-self-end">
                         <ul class="navbar-nav mr-auto"> 
                           <li class="nav-item dropdown">
                            <a class="dropdown-toggle" data-toggle="dropdown" id="navbardrop">
                                <img src="http://media.buzzle.com/media/images-en/illustrations/symbols/1200-12627598-eagle-symbol.jpg" class="profile-picture"/>
                            </a>
                            <ul class="dropdown-menu">
                                <li><a class="dropdown-item" href="#">Newsfeed</a></li>
                                <li><a class="dropdown-item" href="#">One Drive</a></li>
                                <li><a class="dropdown-item" href="#">Sites</a></li> 
                            </ul>
                         </li>
                       </ul>
                   </div>

                  <!-- Close Button -->

                     <div>
                        <button class="close" aria-label="Close" type="button" data-dismiss="modal">
                            <span aria-hidden="true">
                                <img class="close-button" src="/sites/dscott/tmfds/SiteAssets/Images/CloseButton.png" alt=""/> 
                            </span> 
                        </button> 
                     </div>

               </div>

这是我的自定义 CSS：
