In case of restaurant PoS Self Order, there happen to be many options to select according to an especific product, if I establish variants on a product, it will present these variants as different products (ex: prod (var1, var2), prod (var1, var1), prod (var2, var2), prod (var2, var1)) Instead of giving me the options once I select that product. Is there any way to make this option list when you pick one.
