Hey there!

I would be very grateful about a helpful answer!

I want to set up Product Variants for multiple selection rather than being mutually exclusive per attribute.

A good example would be pizza:

You want to be able to select as many toppings as you wish from a single list.  Currently, you'd need one attribute called Toppings, but you can then only select one of the values, e.g. mushroom, or red onions, or pepperoni - but we'd want to select multiple values, e.g. red onions and pepperoni.

It would be great if there is a solution out there, where I do not have to customize anything. Does anyone have an idea? 

Many thanks

Luis
