you can set default values.
you can use JS
The problem with simply setting the value to NULL using JS (and it's even more obvious if you set a default value) is the user sees the word NULL, which looks unprofessional IMO.
I have a blog post coming out next week where I show how to set the value to NULL while the field still looks empty to the end user (and no, it doesn't use a hidden field!).
In other words, instead of this confusing experience:
This smoother one:
Ah yes, I admit I forgot that the form field is still visible for a split second when you change values that way.
I would then probably just use js to add hidden fields for the fields that are empty and set the values of those to NULL. It might be hacky but I think it should work.
