So you basically have two options…
You can use ‘Full List’. This will load everything in that list. BUTTT, it might now be your best option because full list doesnt allow you to control the height of that element.
(Screen shot below)
Now what i do to avoid this issue is this:
I use two repeating groups. One contains the list (Content List) I want the user to see/interact with.set to ‘Full List’
And the other is a Vertical Scroll List. Then I put the Content List inside of that Vertical Scroll list.
Then just like that I’m able to load a full list while still being able to control the height at all times.
Vertical Scroll List
PS: Set your Vertical Scroll list to have only 1 cell to make it easier to grasp.
Also make sure you only let the data source for the Vertical Scroll list have one item. Do what i did in my screen shot to ensure this. “Current User :converted to list”
Let me know if this solves your issue.
