Hello,
I am programming an app which includes to edit fields that creates arrays and based on the length of these array I want to display a new set of edit fields.
The solution I found for this problem is to make a lot of if statements when the length of the array changes.
Is there a more efficient way? I dont know if it is possible to group edit fields in some way to make this easier.
Thank you for helping!
