How to display all products from the main category and from its children?

Question

WordPress

I'm very dumb.
There is a category in it child. Products in each category. How to display products in the main category from all subcategories and have a list of subcategories?

Answer 1

First get the list of subcategories via get_categories. They are processed by the foreach loop. Inside this loop, you request products via get_post and display them in the same way.
