Add Subcategories/subcollections
Add subcategories/subcollections to your online store, as they help in organizing your products into several categories. Nested collections — which means — collection within a collection, is not enabled by Shopify.
Therefore, the implementation of subcategories/subcollections will allow you to create multi-tier category navigation. It will be done via the creation of a page enlisting your preferred collections.
If you select the task "Add Subcategories/subcollections" you will get to use the creation of functionality and guidance for creating subcollection lists.
