You can add several variants of one product to the catalog.
Variant is an option that helps you to specify additional parameters of the product - color, size, etc.
How it works
To add a new product variant, go to the CRM section - Inventory - Product catalog.
Select a product from the list.
Click the Create variant property button and select one of the options.
Read more information in the article: Product properties.
Specify the field name and add list items. Click Save.
If you enable the Show in Online Store option, the product will be placed in your Online Store.
Click the Add variant button.
A duplicate of the product will be created. You can now specify its additional parameters.
Click Save when you have configured additional parameters.
