This question already has an answer here:
I am writing a blog system and I want when users hover the tags listed beneath the post a tooltip appears and show related contents to the tag. Just like what we have here in stackoverflow. Just hover the tags to see what I mean.
I know the ajax stuff and database driven details tobthis issue. What i am stuck on right now is how to make that popup. Is it javascript or what.
Any help that can give me a clue to do this would be appreciated
