I have a product (a modular bed frame) that has a lot of options (size, wood, height, leg style, finish, etc.) which makes for a product that has hundreds of potential variants. It seems that Squarespace is quite limited in the way it handles inputing product variants/options. As in each and every possibility must be input manually and separately. Is there a plugin that helps with that? Or some technique that I am overlooking? Other platforms have much more highly developed variant engines. Is this functionality something that could be added to a squarespace back end by a developer?
