title: dynamic select_tag?
body: <p>I have posts that gets filtered based on location, category and tags, so I have 3 select_tag that chooses the filtering. The items in the select_tag are of this form name (num) where num is the number of posts that satisfy the filter. As you can see if I have Boston (20) for location and Computer (10) for category, there's no way to tell how many results I will come up with if I specify both Boston and Computer. I was wondering if after I choose Boston (20), the select_tags will update itself so Computer (10) might become Computer (5) and so on.</p>
