Say, there is a page /catalog which is a parent to all products. I can have permanent routes with pages, e.g. /catalog/product/1, /catalog/product/2 etc.
But a user can choose any other page to be a parent page for catalog products, e.g. /stock.
How can I render products data on a variable node, e.g. /{variable-page}/product/{id}?
It's easy with multiple pages for each product - just make a block 'product_list' to render all products on a parent page and a block 'product' to render each product on a child page of the product_list.
But I don't want a million pages. I need only 1 page to render DB content of any product under a parent page where its name and route can change.
