The Sub Collection section displays related collections in a horizontal list, allowing customers to quickly navigate between categories within a collection page.
You just need to select the collections you want to display in the Sub Collection section.
The collection image will be taken from the image you upload for each collection in Shopify. If no image is set, the image of the first product in the collection will be used automatically.
If you want each collection to show a different sub collection list, you can use metafields to configure this individually.
Step 1: Create a metafield
Step 2: Go to each collection and assign collections for sub collection metafield.
