A CSS Method for Category Filtering?

· Best Practices, Information design, Weblog Concepts

Would it be possible to put check boxes next to my navigator links and have them drive CSS logic to hide entries that are only associated with unchecked categories?
Would this be something like the Jakob/Zeldman buttons for switching from serif to sans-serif? I think I may need to ask a CSS guru, such as Eric Meyer or Eric Costello .
