Thanks for your reply!
There are no errors. I took a snippet of my code, may be I missed something.
As for the control's setting, I can't use prevent add/delete setting, because f I do that I can't add rows programmatically as well.
Below are the steps performed to view the form and fix the repeating section scroll:
PFA updated form. Hope this helps!
Even if I set the height to 700, once I programmatically populate the repeating section, the scroll bar appears unfortunately.
Can you inspect the repeating section panel with data populated and check for the CSS which is cause of the scrollbar to appear? Just like how I have mentioned earlier.
