How to render products from subcategory

Is there any easy way from code perspective to render product on a category, which belongs su subcategory.

|_MainCat
|    |_SubCat-1
|    |_SubCat-2
|
|_Product-of-SubCat-1
|_Product-of-SubCat-1
|_Product-of-SubCat-2

or at least to get list of categories that product belongs to, that could work as well.

Thanks in advance!

I think you need to check setting:

Admin panel > settings > catalog settings > find Catalog pages section and checked following setting.    

Include products from subcategories

Thanks, but this will not solve my problem, as I mentioned I need this within the code, because I want to use only for one particular category template.

Appreciate any help :) please someone

Many thanks!
