Displaying product details on index page

[truetaurus]

On my index page I have this featuredproducts module being rendered. But it is very basic as I can see, it does not allow you to select quantities, groups etc.

 

How could I add additional fields such as any combinations/groups i have and selecting quantities? See the image below. I figured out how to add Quantity, but how do I add extra custom group data like i have for Quality?

So found a solution, added this to the featuredproducts.php:

 

$this->assignAttributesGroups($rawProduct);
