@aryanbhat One note regarding your change. This will have the effect of changing the form height when the field appears and in many cases when you have other things under the form, this may not be deisrable.
I would make the function optional with a default value in order to preserve backward compatibility.
Just a suggestion.

Work great thank you 👍 💯
