Create 2 or more products on Hoplix with the same sku, without using Hoplix's “combine” feature.

Once the products have been created on Hoplix, proceed with exporting them to Shopify.

How to combine multiple products on Shopify:

Go to Shopify and open the Products section.
Change the name of the first exported product.
Set up the product and add color variations.

Please note: Remember to use English colors and only those proposed by Hoplix.
To add a variant, take the SKU of the second exported product and use it for the new variant.

Second Product SKU and Status Management:

Enter the SKU of the second product in the first product's tab, in the variant section.
I recommend leaving the second product in draft status to avoid confusion.
Add product images: Upload the product image to the first product's tab on Shopify.
