Hi,

I'm trying to add a drop down to the categories sidebox that will allow a user to see a) all stock, b) Only items in stock, or c) only out of stock items. Once the selection is set it needs to stay selected, until changed by the user.

This needs to affect the categories list, and the all the methods to display products.

Not an easy task, any help would be appreciated.

Thank you,
Mike Cassidy
