OpenCart Community

hello
I'm trying to find a solution but still no luck. I want to display all products from subcategories to parent category.

I'm using Opencart 3.0.2.0

Not sure i understand your question??
Your title says you want to show ONLY subcategories on category page but in your post you say "I want to display ALL PRODUCTS from subcategories to parent category"
Could you clarify exactly what you are trying to achieve
