title: Add an option to a g:select after it loaded elements dynamically?
body: <p>I have a select like this:</p>
  
  <pre><code>&lt;g:select style="width: 500px;;" name="ftp" value="${ftpResource.host[0]}"
                from="${ftpResource.host}"
                optionKey="${ftpResource.id}"
                keys="${ftpResource.id}" /&gt;
  </code></pre>
  
  <p>but I want to add a message in the drop down list and then more information, like:</p>
  
  <pre><code>ftp1
  ftp2
  ftp3
  this message
  ftp kind 1
  ftp kind 2
  ftp kind 3
  </code></pre>
  
  <p>I tried this: </p>
  
  <pre><code>from="${[ftpResource.host, 'Message', ftpkindResource.host]}"
  </code></pre>
  
  <p>but it displays it inline, How can I do that?</p>
  
  <p>(and taking a chance of this post, with property 'keys' can I set the Ids live values to send them in params for each option?)</p>
