NOTE:
I have created a wishlist idea. If you are looking for this functionality, please upvote the wishlist:
Ability to make lists nullable
Lists that can be nullable are possible in FF, but it seems like items from lists cannot be made nullable, is this true?
I would like to be able to use something like this in custom functions, for example:
Is this a limitation of FF? There is only a checkbox to make the whole list nullable, but not the items? (even outside of custom functions)
We would need this functionality many times in our software, should I make a feature request or are there other ways to achieve this?
