The use of collections is optional as you can create your products without them. In terms of design you can just set up links in your menu to go directly to product pages rather than collections: https://help.shopify.com/en/manual/online-store/os/menus-and-links/editing-menus
Thanks for your response. I tried to check the link but I still can't manage to display all individual products in my store without it being under the Collections page. I really have a small category so i think it will be a bit pointless to put them in Collections. Is there any other way I can display the products on the homepage?
