I've been customizing the ********* Power Filter file, power_filter_skin3.tpl, to include checkboxes instead of links. I have it working, but there's still one last feature I'd like to implement.

Currently on 'Brand' and 'Price', the user can select multiple brands or price ranges and the results will return the products for all selected. However, when I choose a product class, like 'Size', it automatically hides the rest of the values for that class. In other words, if I choose a size of Large, it automatically hides S, M and XL. I would like the user to be able to select multiple sizes.

Does anyone know how to do this, or at least able to point me to the files involved in making this change?

Thanks,
Michael
