If you're using a newer version of any of our themes, you'll now have the option to use a template called 'collection.sub_collections.liquid' with a collection.
This template will let you feature a menu (previously known as a linklist) of collections and products at the top of your collection, or by themselves.
The featured menu (images of collections) is determined by the collection name, in order for the menu to be connected to the collection page they just need to have the same name.
In this example we'll be creating a collection called 'Number Series' that will feature a few of the number collections. The first step is creating the collection and telling it to use the 'collection.sub_collections.liquid' template:
Now we have the name of the collection we'd like to use so we can create a menu with the same name, and link to the items to feature:
That's all! You'll now have a collection page that will feature other collections :)
This could be used to feature related collections, sub-collections that could act as pseudo-filters, etc. Enjoy!
