I'm trying to design a section for clothing and I created a collection for Men's Clothing and I would like to create sub-collections inside of the main collection for types of clothing such as dress shirts and t-shirts. Is this possible to accomplish?
Unfortunately there isnt the ability to add sub collections. Your best option would be to tag the products something like "dress shirts" that you want to fall into the mens dress shirt category. Then when you want to direct people to that part of your collection just link them to "/collections/mens-clothing/dress-shirts".
This would take you to all products in the Mens Clothing collection tagged dress shirts.
If you'd like to make any edits to your store, please send me a personal message and we can discuss what you'd like to accomplish :D
