Product options & variants

Site URL: https://www.colazioneinbottega.com/

Good afternoon,

We've setup & purchased the Advances Ecommerce option for food ordering.

Is there a way to have one option with multiple variants?

Ex. Brioche Vuota (1.50 EUR)

With an option to add filling: Chocolate, Pistacchio, etc.

So one option (add filling) w/ choice of filling (variant + price [.50 EUR addtional for a total price of 2 EUR])

Lastly, is there a better option than Ecomm, say an extenion I can add geared towards a restaurant?
