Product Listing Group by Category

-- HikaShop version -- : 2.6.2

Hi

I have a menu which is a product listing, wherein the sub-elements filter is set to Grouped by Category, is there any option wherein I can have the main Category, sub category and the products display?

The categories are not in proper order as I want to have.

Here's the link www.enigma-phil.com.ph/enigmanew/pricelist/product/listing

Motherboards are in between of processors, which is wrong. ( BASIC INTEL PROCESSOR BASIC AMD PROCESSOR, etc) has a Main Category which is Processor.

Here's the Summary of what I want to display,

Processor > Sub-Processor Category with the Products
Motherboard > Sub-Motherboard Category with the Products

and so on.

Any help?

Thanks in advance

Gary
