Add to array in specific cell in database

Hi all,

I have a project that utilises a third party plugin with its own forms. I can populate dropdown choices in the admin interface in the back end, but would like to give certain users (access control isn’t an issue) the ability to add to the choices array of specific questions using a separate form.

How do I go about this with GF? It would only be a single text field to add one option at a time to an existing array stored in an options field in a specific row, in a specific table. We have a gravity forms elite license if any add-ons can aid the process?

I’ve got limited php skills, but understand principles of sql, php, themes, functions etc and crucially can follow instructions :grin:

Any help or direction would be gratefully received.

Thanks in advance!
