We have some campain categories on our shop with the follow structure:
Campain category (no stream)
- Campain sub-category 1 ( stream A )
- Campain sub-category 2 ( stream B )
Out of the box, if we click on any „Campain sub-category“ (1 or 2) the items from product streams ( A or B ) are displayed. But, we would like to see the products from stream A and B when we click on Campain category (parent category), is that possible?
