title: IBM ICN 3.0.3 - Ugly display of a ChoiceList for a mono-valued Property in the Content dialog
body: <p>Given a Document class, a mono-valued Property of the Entry Template is associated with a ChoiceList. This works well if the ChoiceList has no "sublevels" (Choice).</p>
  
  <p>When a Group Choice is added and the user tries to fill the property, the dialog becomes ugly, as well as displayed below:</p>
  
  <p><a href="https://i.stack.imgur.com/N0LVc.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/N0LVc.png" alt="Entry Template monovalued Property Control"></a></p>
  
  <p>Is there a way to automatically unfold the tree view for the root Choices, and moreover to remove the "none" label ("Aucun" in french) as well as the symbolic name of the ChoiceList (blurred here)?</p>
  
  <p>Do I have to write a Plugin to fix the issue?</p>
  
  <p><strong>Update.</strong> The purpose of "Aucun" here is to empty the field. </p>
