Listingpro theme make form fields optional?

I am currently editing a clients site and they want to make some of the form fields optional.

I looked around the code as well as skimming the wordpress backend to see if there was an option to make it not required but I couldn’t find any.

Appreciate the help!

My current idea is to take out the form fields from listingpro and manually code in the optional fields but then there would be a whole slew of other tasks I’d need to do to make it work.

never mind. Found the code inside submit-listing.js
