title: Multi select dropdown showing additional dropdown
body: <p>I am creating a multi-select dropdown using bootstrap this is the html :</p>
  
  <pre><code>&lt;form id="multiselectForm" method="post" class="form-horizontal"&gt;
    &lt;div class="form-group"&gt;
      &lt;label class="col-xs-3 control-label"&gt;Browser&lt;/label&gt;
      &lt;div class="col-xs-5"&gt;
        &lt;select class="form-control" name="browsers" multiple="multiple"&gt;
          &lt;option value="chrome"&gt;Google Chrome&lt;/option&gt;
          &lt;option value="firefox"&gt;Firefox&lt;/option&gt;
          &lt;option value="ie"&gt;IE&lt;/option&gt;
          &lt;option value="safari"&gt;Safari&lt;/option&gt;
          &lt;option value="opera"&gt;Opera&lt;/option&gt;
          &lt;option value="other"&gt;Other&lt;/option&gt;
        &lt;/select&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>and this is the JS: </p>
  
  <pre><code>$('#multiselectForm').find('[name="browsers"]')
    .multiselect({
      enableFiltering: true,
      includeSelectAllOption: true,
      // Re-validate the multiselect field when it is changed
      onChange: function(element, checked) {
        $('#multiselectForm').formValidation('revalidateField', 'browsers');
        adjustByScrollHeight();
      },
      onDropdownShown: function(e) {
        adjustByScrollHeight();
      },
      onDropdownHidden: function(e) {
        adjustByHeight();
      }
    })
    .end();
  </code></pre>
  
  <p>But the required out is as follows: </p>

  <p>I dont know why the box at the bottom with blue combo boxes appears, I want to remove that.</p>
  
  <p>These the files I have included in my project, need to identify which one of them is interfering with multiselect dropdown :</p>
