Hi @rctneil
Thank you for your interest in the Filter Everything plugin.
Well, you can simply use one option “Decaffeinated” and apply it to the needed products. Use the “AND” logic for it, so when you check the term “Decaffeinated” it will show only products that have “Decaffeinated” applied to them. When unchecked it will show all of the products.
But if you want to make something like a switch you would need to use custom coding for it.
