A Relation Group is a kind of ad-hoc list consisting of a label - like ‘Winter Accessories’ or ‘Female Choice’ - which products may then be added to.
Whenever a product in the relation group is shown in frontend, the other members of the product relation group can then be shown as ‘Related products’.
To create a relation group:
- Go to Settings > Ecommerce > Product Catalog > Relation groups
- Click New in the toolbar
- Enter a name
When a group has been created, it appears in the Related groups dropdown in the product ribbon bar.
