TL;DR: Change VAT for items in a specific category.
There is the need for a change in VAT in the cart/checkout page. If the product only contains products from a specific category, then change/reduce VAT to a fixed value.
Example 1: if cart has 4 products from category "helmets", change VAT to 5%.
Example 2: if cart has 2 products from category "helmets" and 1 product from category "gloves", leave VAT unchanged.
Example 3: if cart has 1 product from category "helmets", change VAT to 5%.
Example 4: if cart has 1 product from category "gloves", leave VAT unchanged.
Is it possible? Any ideas? Could anyone point me to the right direction? Thank you in advance.
