I want to add the simple filter: Brand and Engine
All products have a Brand and Engine attribute.
When you click a Brand and go to Engine filter it shows EVERY engine for every brand. I need it to work like this:
If customer choose brand “TOYOTA” then Engine filter should only show the matching Toyota engines that are connected via product pages (attributes) not all engines as there are too many eg BMW, Nissan, etc
I use custom layout pages
