title: Show static non-clickable heading in AutoCompleteExtender list
body: <p>I have an AutoCompleteExtender from the Ajax Control Toolkit. I need to have a heading in the dropdown list that shows how many items found, but it should not be selectable as an item.</p>
  
  <p>I have tried this using jQuery, but even when I just add as a div, it is still selected as an item into the text box when I click on it:</p>
  
  <pre><code>function clientPopulated(sender, e) { 
      var completionList = $find("AutoCompleteEx").get_completionList();
      var completionListNodes = completionList.childNodes; 
      for (i = 0; i &lt; completionListNodes.length; i++) { 
          completionListNodes[i].title = completionListNodes[i]._value.split(':')[2]; 
      } 
      var resultsHeader;
      if(completionListNodes.length==1000)
         resultsHeader = 'Max count of 1000 reached.&lt;br/&gt;Please refine your search.';
      else if(completionListNodes.length&gt;0)
          resultsHeader =  completionListNodes.length + ' hits.';
      else 
          resultsHeader = msg_NoObjectsFound ;
      jQuery(completionListNodes[0]).before('&lt;div&gt;' + resultsHeader + '&lt;/div&gt;');
  }
  </code></pre>
