I'm currently trying to wrap my head around how I go about allowing my products to be filtered by custom attributes I have set for products. For example, I have a products called Computer 1. It's worth £100.00 and has a 1.2 processor with 1GB of Ram. I also have in the same category another computer called Computer 2, worth £150.00, 1.4 processor and 2GB. How could I list the varying attributes in the sidebar so people can narrow down a huge range of products by individual attributes? For example, if you view the following link:
You can see that they allow for people to filter their products by Price, Manufacturer, etc. How would I go about doing that with my products and their attributes. Any help would be really appreciated. I've seen a few tutorials but they seem to want to play with the Mage Controllers, and as I understand it, I'm meant to leave those files of my website alone.
