How To: Group Reviews by Product
Product groups are mainly used to group same/similar products but with different variants, so the reviews are shared across the grouped products. So for example, if you have a bottle but have created it as 2 separate products for 2 different sizes:
memobottle A6 - https://www.gatomall.com/products/a6-memobottle
memobottle a5- https://www.gatomall.com/products/a5-memobottle
We created the group with the relevant product IDs, and named the group 'memobottle'
If you visit the above product URLs, you'll see that the reviews for both of the products are shared on the product pages, meaning to say A6 memobottle reviews will be shown in A5 memobottle product page, and vice-versa.
Deleting the group will not delete any reviews, the reviews will simply be unshared among the grouped products.
