I have some products who belong to more than one category. And each of these categories have products with different kind of taxes.
So, the 'standard' categories have not any tax rules.
Then, I have created some categories (let me say 'categories tax') only to define tax rules, and then I have assigned each product to the 'category tax' correctly. If the 'categories tax' are published, the products have the tax assigned correctly, but If I unpublish these 'categories tax', the products have not tax assigned.
Milbo, how must I use the unpublished categories because in your post you say ' the tax system is quite powerful with combination of unpublished categories.' but I donít know how make it works...
Thanks in advance
