Ajax Enabled Enhanced Layered Navigation

Hi,

I am using the Ajax Enabled Enhanced Product Filter on my website to allow customers to sort products in real time based on attribute. This is an official plug-in from WooThemes, and only allows filtering based on attribute.

My question comes, as attributes seem to be for things such as, Small/Medium/Large, Color, or any other characteristic that would be used to select a variable product.

I want to be able to sort my products by similar characteristics within the product filter plug-in, by something like “part of the body”. This would group all products related to “arm”, or “knee”, or “back”.

Is it possible for me to use attributes for this? When I tried to add attributes for this, I ended up with drop down box on the product page, or a text box on the product page – where the customer would select the attribute – similar to “select size”, although there was only the one option of “knee” for the “part of the body” attribute.

How can I make what I am trying to accomplish work with attributes?
