title: Image does not show up in selectbox (Twitter Bootstrap plugin)
body: <p>I am trying to create a select box that shows all Twitter Bootstrap Icons with its text. Therefore I am using the <a href="http://silviomoreto.github.io/bootstrap-select/" rel="nofollow noreferrer">Bootstrap-Select Plugin</a>. One of the images shows up in the list, but the rest is somehow hidden. </p>
  
  <p><img src="https://i.stack.imgur.com/l5IdL.png" alt="enter image description here"></p>
  
  <p>What do I have to change in order to get the list of all listed icons with its text?</p>
  
  <p>JS:</p>
  
  <pre><code>&lt;script src="source/bootstrap_select/bootstrap-select.js" type="text/javascript"&gt;&lt;/script&gt;
  
  &lt;script type="text/javascript"&gt;
      $( document ).ready(function() {
          $('.selectpicker').selectpicker('');
      });
  &lt;/script&gt;
  </code></pre>
  
  <p>HTML:</p>
  
  <pre><code>&lt;select class="selectpicker"&gt;
      &lt;option data-icon="icon-search"&gt;icon-search&lt;/option&gt;
