Hi Anthony,
When you add a collection to a store it should allow you to select the collection to display in your shop element. (If you want this on other pages, its easiest to duplicate the page) - to change collections displayed by the “shop” element. Simply select the element, select settings and choose the collection you want displayed under the “Collections” tab. -
I have added a screenshot of this below.
Hopefully this helps - feel free to ask further questions or for further advice on this :)) - I’ll try and get back to you as quickly as possible!
Thanks,
Elliot
