How $Items Is Assigned To The Products Block Tpl File

How $items is assigned to the responsive/templates/block/products/products.tpl

Where do we assign items for products tpl file.

where is this file called and how to show only selected products.

{include file="blocks/list_templates/products_list.tpl"
products=$items
no_sorting="Y"
obj_prefix="`$block.block_id`000"
no_pagination=true

....

}

I need the answer for this question too, but I'm sure it's related to the blocks schema.

Right. if the function is not specified, the system uses fn_get_[object_name] function. It should return array the first element of which is assigned to the template as $items variable
