title: Sitecore Tree list datasource - VersionExist
body: <p>in the Sitecore Treelist control, I want to get only the elements listed, which have a version on that language.</p>
  
  <p>I did a search and found out that there are parameters for including/excluding items/templates. But I cant give in a condition like Versions.Count > 0</p>
  
  <p>Is there a way to do it by passing a parameter to the datasource field of the template?</p>
  
  <p>Or do I need to overwrite the treelist control?</p>
  
  <p>Thanx</p>
