Hi guys,
let’s say I am on a product page and my current product has the product type “tennis racket”. Now I’m longing for a featured collection section that displays only products assigned to the same product type as the current one. How am I able to communicate to the theme, that it has to get the type from the current product and display more of those? 
You can do this with the search and discovery app by Shopify. It lets you add/choose product recommendations for each individual product. Pretty easy to setup as well. No learning curve whatsoever and the app is free since it’s from Shopify
Hey, I’ve wanted something similar for my own store too. The idea is basically to grab the product type from the product page and then tell your featured collection section to only pull items with that same type. Most themes don’t have this built in, so it usually means tweaking the Liquid code a bit.
I won’t go too technical here, but just know it’s about connecting the current product’s type to a collection filter. If you’re not used to editing theme code, an easier route is to use an app that handles “related products by type.”
When I set mine up, I actually had to get a bit of help to make it work properly so don’t worry if it’s not obvious at first.
