Ok, I understand that when using filter fields, it will not display a filter link if that option will produce 0 results. In the site I'm building, this is somewhat problematic as the filter items are styled and having them disappear depending on the current filter values disrupts it.

So, what I would rather happen is leave the the option there but instead of it being a link, it be a non linked <span> so it can be styled (greyed out or something).

This would allow for a consistent UI no matter what the user clicked on. Does anyone know where I might look to possibly add this in myself?
