Hello everybody.

We're using Odoo 10 on our office and we have a lot products with variants to showcase on our website.

Let me explain our problem: we have a product that has 2 different variants (Nib size and Color). The thing is that we only sell certain nib sizes in specific colors.

I created the product and the variants. I archived the variants that don't exist in our store. As an example, we have a product with the nib variant of 0.6mm with all colors available, except the color black. The black variant is only available on 0.4mm and no other color is available in that nib size. So, when I go to the website, I can't choose the black-0.4mm option. When i try to choose it, it appears a "Product Unavailable" message and I can't return to the variant options.
Is there an option to solve this? I hope I explained myself, english is not my native tongue.
