I try to make an app as a questionary, I dont know how to figure this error out.
AttributeError: 'CustomItem' object has no attribute 'delete_item'
I know what does it mean, that CustomItem is another class so it hasnt that def, but when i copied that def into CustomItem class, it hasnt object panel. So is it possible to connect another class ?
