I'm building a custom app, and trying to build in some navigation. This is going to be, select a collection, choose a filter (based on tag) and then view products.
After some perusing of the documentation, I cannot see a way of returning products with a certain tag applied, from a specific collection.
I can see 'collectionByHandle', but this seems to provide no way of querying products by tag. I can see a way to query products by tag, although this isn't much use as I can't pass a collection handle filter. Is my only option to do this manually and join them up myself?
When querying products within a collection, you're not able to use the query argument to filter products further. I believe you would need to manually connect them.
