Dokan new-product custom fields

Hello,

I’m using Dokan to build a marketplace for clothes.

I’d like to add some custom fields in the product page, that sellers will have to fill when creating a new product.
For instance, I’d like them to specify the fabric(s) of the clothe they’re creating.

If I understood well, Dokan can’t do that on its own and no plug-in neither, I’ll have to add some custom code.

Does someone know how to do that please ?

Thanks a lot
