From your example, it seems that you are looking for a way to separate a list of items using divider lines. I would advice to use qListView, since qListForm is mostly used to display or edit a single item at a time.
In your el list example, using qListView, you could assign a column for Group By in Sharepoint list, and configure qListView to display the fields using Group By on the same column. In that way you get a nested structure with items with the same value for that field grouped together, which provides some form of visual separation, if not exactly a bold divider line.
