Yes, you can add a new variant to an existing product that is already published on your Shopify store. There are two ways you can achieve this.
First method: Creating the variants directly from the Product Detail Page
1. Find the product you would like to add variants to in your store and click on Edit Design
2. In the sidebar on the left of the Product detail page, you will be able to select the new variants (new sizes or colours, etc) and adjust the design if necessary.
3. Publish the changes
Note: For this to work, the product must be:
- Created in Gelato Dashboard and don't have not connected or ignored variants
- All variants must be connected to the same product type. This means it will not work if one or more variants are not of the same type (eg. Some variants are posters with frames, some are posters with hangers, and some are posters without frames)
Second method: Create the variant in Shopify and then linking it in Gelato
1. Create the new variant manually in Shopify, e.g. by clicking on "Add variant" or by duplicating an existing variant - see screenshots below.
2. Please go to Gelato Dashboard and in the section 'Stores', enter the store page with all products and click on "Sync products" (the button is located on the top right corner of the page). After a while you will see a new variant as "Not connected".
3. Connect the new variant to Gelato as shown here.
Note: If you need to add many variants, it might be faster to create the product from scratch following the steps described here.
