More Then One Variant On Features

i am currently building a multi vendor store for digital products.

Vendors need to be able to specify which countries their products can be sold to.
I have created a "Country" feature with the countries as variants. Unfortunately you can only select one country at a time and not several at the same time.
But at the same time it is important that I have the filter "Country", based on this feature for the product search.
I would be happy if I can be helped.
Kind regards

Have you tried Multiple checkboxes feature type?
