How can I add a multiple choice of sub products to a chosen product?

Hello,

I am using the restaurant theme form, I am trying to give my customers the option to choose a "menu" with different choices inside, that may or may not contain price changes to the product, how do I do that? (attached example of such a form)

Thank you
