So I’ve got an application that includes several tooltips for providing a bit of “help” information to users. Basically, the user hovers over a question mark image and then the help text is displayed in a stylized widget that behaves like the browser tooltip.
Being generally all about using jQuery for my ajax / UI needs, and also being generally lazy about writing more code than I have to or reinventing the wheel, I was using a jQuery tooltip plugin by Jörn Zaefferer: nice and easy to set up; simple, clean interface — works great in the simple case, where everything is visible and static on the page.
