I am using the Venture theme and have customized the theme some to show a navigation on the front page of my store with the menu items and image (pic below). These 4 items are all set up as Collections.
When you click on one of those pictures, it takes you to a page with all of the products.
Is there a way to add another layer of navigation in there? So if you click on "Camping & Hiking Gear", it would take you to a page which shows the next tier of menus for items such as "Backpacks", "Tents", "Sleeping Bags". Then when you click on "Backpacks" it would take you to all backpacks.
