- In Shopify, collections are based on products, not variants.
2 . If only a few variants from each product matter, you can create new products for those specific variants and add them to a manual collection.
For example, create a product like:
Walnut Block – 1.5” x 1.5” x 18”
Cherry Block – 3/4” x 3/4” x 6” - Then include these specific items in a manual collection like “Best Sellers”.
