I have set it so that only articles in the tree are showing. I have found how to customise to hide various tabs and options for when you create/update an article but I was also wanting to hide the template/advance settings/Comments/Resource Groups in the parent folder (see attached). The user just needs to see the list of articles and be able to edit or create a new one.
Also, is there a way to hide the parent container for the articles and just show the children? The user doesn't need to this page as it just sets the template.
