Filter widget per category?

Hi,

I’m setting up a webshop for musical instruments. And every category has different attributes, and therefore different filters.

For example on the Guitar product overview only filter must be available that refer to Guitars given attritubes. These are not the same filters on the Piano product overview.

A simple solution is to create a unique sidebar widget are per category. But that makes it too difficult to manage with a lot of categories and attributes.

What options do I have to create different sidebar widget filters per category?

Thanks alot!
