I'd like to create a popup (like a div) that appears when you do a mouse-over of a little icon at the bottom of my screen.  The little icon is called "more", and it should show a white box that contains some icons, associated text, and the icons and text should link to pages.

I looked at the menu feature of jquery-ui, and it seems that the icons provided are not icons that I would provide, but rather general icons.

So what is the best way to go about this?  (For an example, on www.google.com, you can see a little box at the top with 9 squares in it, and if you click on that, a big white box opens up, with icons that can be clicked on.

Thanks.
