Hi @NabeelNQ,
Thanks for updating.
A scrolling screen could be added not just limited to a form
It seems that you are using Patch function, so I have made a simple test likes below.
Add a Scrollable screen, add data source to SharePoint List A.
In the added canvas, insert multiple Text input boxes.
At the bottom of the data card, add a button control and set its OnSelect property with the following code:
Patch(ListA,Defaults(ListA),{Title:TextInput1.Text,AA:TextInput2.Text,BB:TextInput3.Text,CC:TextInput4.Text,DD:TextInput5.Text})
Open preview mode, you could get all the boxes by scrolling down to the bottom of the screen.


Best regards,
Mabel
