Space supports two methods to display products as swatch options. This is helpful if you want to split one product into separate listings but maintain visibility for each option. When this is set up, customers will see sibling products as options so they can easily select different options or colors.
The app can be used to link multiple product together. Visit the Shopify help center to learn more about this feature.
If you have multiple versions of one product split into different product listing it may be hard for customers to find the option they want. Using the “Linked products” block you can display additional products as options on your product page.
