title: Missing pagination dropdown icon using Angular ui grid
body: <p>I am developing a table with pagination using Angular ui-grid. But somehow I am missing the drop arrow from the pagination dropdown as you can see in the following picture.</p>
  
  <p><a href="https://i.stack.imgur.com/ea3uY.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ea3uY.png" alt="enter image description here"></a></p>
  
  <p>When I click it, it opens like dropdown, but I need the down arrow to indicate that its a dropdown. </p>
  
  <p>I am using following css libraries</p>
  
  <pre><code>&lt;link rel="stylesheet" ng-href="libs/bootstrap/3.3.6/css/paper.bootstrap.min.css"&gt;
  &lt;link rel="stylesheet" type="text/css" title="Style" href="libs/angular/ui-grid/3.0.7/ui-grid.min.css"&gt;
  </code></pre>
  
  <p>I config gridOptions as following </p>
  
  <pre><code>paginationPageSizes: [10, 20, 50],
  paginationPageSize: 10,
  data: 'historyData',
  enableCellSelection: true,
  enableFiltering: true,
  enableHorizontalScrollbar: 1,
  treeRowHeaderAlwaysVisible: false,
  showTreeRowHeader: true,
  enableGridMenu: true,
  exporterMenuCsv: false,
  exporterMenuPdf: false,
  </code></pre>
  
  <p>Below is my html code</p>
  
  <pre><code>&lt;div class="container"&gt;
  
  &lt;div id="gridDiv" 
      style="-webkit-animation: slideInRight 0.3s; -moz-animation: slideInRight 0.3s; animation: slideInRight 0.3s;"&gt;
      &lt;div id="historyGrid" ui-grid="gridOptions" ui-grid-edit
          ui-grid-cellnav ui-grid-move-columns ui-grid-resize-columns
          ui-grid-save-state ui-grid-pagination ui-grid-pinning
          ui-grid-grouping ui-grid-exporter class="grid"&gt;&lt;/div&gt;
      &lt;div class="watermark" ng-show="!historyData.length"&gt;No upload
          history available&lt;/div&gt;
      &lt;div&gt;
          &lt;p&gt;
              &lt;img ng-src="{{contextRoot+'pics/addScanIcon.svg'}}"
                  alt="addScanIcon"
                  style="width: 25px; height: 25px; cursor: pointer" /&gt; &lt;span&gt;
                  Click the icon for a specific policy to upload additional documents
                  to policy.&lt;/span&gt;
          &lt;/p&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
