Today I was looking for ideas for displaying tooltips on a client’s new site… This is what I ran across, I hope it’s helpful.
Tooltip Scripts and Extensions
I like Tipsy and have used it before a few times, it creates Facebook-like tooltips.
Prototip uses Prototype and Scriptaculous to create a variety of AJAX tooltip styles. Old-school, some use images.
The successor to Prototip, Tipped uses Canvas and jQuery to create some very nice-looking and more complex tooltips; also has an API for custom cases.
