Defining product variant and sub-variant is Step 2 in the Upload Product Page. Color is a system pre-uploaded variant. Click the variant dropdown menu and choose color if it’s the appropriate variant of your product. Choose ‘Others’ when you wish to key in a specific variant for your product other than color.
Once the variant is defined, click ‘Add a Sub-variant’ to add a sub-variant. You may also add a specific sub-variant by clicking ‘Others’.
