An Advanced jQuery Tooltip Plugin – qTip2

Tooltips are tiny user interface elements which are very useful in displaying information "on request" without breaking the attention/focus.

WRD had previously featured qTip and it now has a new version, qTip2, with lots of improvements and new, exciting features.

qTip2 - jQuery Tooltip Plugin

The plugin can display the tooltip in any position wanted, plays nicely with image maps and they can be set to follow any element (handy for drag 'n' dropped and animated items) or mouse.

Tooltips can be styled completely, there is an optional Themeroller support and they can even be displayed as modal windows.

It has built-in Ajax integration and can load any remote data. qTip2's website has lots of creative demos including 3rd part service and various popular plugin integrations.

P.S. The download package can be customized to şnclude only the features needed and a converter exists for upgrading from the 1st version.
