I have this exact same thing in the site i'm building at the moment. It's using jQuery to create some HTML tags. You have to manipulate some CSS to achieve it also such as positioning.
I can't fully help at the moment, I'm at college but when I get home tonight I will have a good look at my code and help you out. I can't fully remember the code now so I don't really want to guess.
