I want to add a category View for the Site using Virtuemart, which shows all Items in each category with the number of items inside each?

Question

i am using Virtumart Version is : 2.6.12.2 If you see this link: http://uae.souq.com/ae-en/ It shows Each category at the Top & the Products will be shown next line Horizontally. i.e:

1) Top selling Items. ---List of the items ....horizontally & at the End a link " Show All"

2) Mobiles

-----Selected mobiles from mobiles category....at the end in the most right hand side.."View All"

3)Laptops ...

4) Bags 5) shoes...etc

It will continue like this for all the major categories.
