Using Magento 1.9.1 and have a problem with Layered navigation and bundle product brands.
I have many simple products that can be part of any bundle product. All of them can be with different manufacturer (brand). If they are part of a bundle, they are marked as "Not visible individually".
I make a new Bundle product, and set some of the simple products as part of the bundle. I also set manufacturer for the bundle product that is different from the children.
In my layered navigation i can see the manufacturer for the bundle product, but also all children. And I would only want to show manufacturer of the bundle.
Only if a simple product is marked as visible in Catalogue, it would show up in the layered navigation.
How do I filter children manufacturer from layered navigation if the child is marked as "not visible individually"?
