Show categories and/or products

Hi there!

Is there a way to show product categories when we choose a brand, instead of just the products?

For instance, we choose Asus and have products on categories like laptops, computers, displays, smartphones, etc. Currently the products are showed all mixed together and this is OK, but it would be great to have a set of options to:
– Just show categories with products of selected brand, and after clicking, the products on that category of chosen brand are showed
– Categories and products after the categories on the same page

Thanks!
