If you’re okay with using extended vertical scrolling, this can be accomplished using the :items until option. For example, the data source of the repeating group could be “Do a search for Users:items until 5”. If you only had 3 Users in your app, the repeating group would collapse to show only 3 cells, and grow to 5 once the app had 5 Users. Lyndon found the solution in this post.
