I've created a custom attribute in Magento, called 'brand_name' and 'brand_id'
I need in each categories, to show all the "brands" available for this categories.
Example:
I've a Shoes category, in my Shoes category I've products with brand name like 'Louboutin' 'Dior' etc...
I'd like to show in a page those brand, then when clicking on it I'd like to show all product which are from "Louboutin" in category "Shoes"
The last part is simpler I think, however I don't really know how to start but I'm pretty sure Magento provides such functionnality.
Do you know which method could I use to do that?
