I'm trying to make a "bubble" that can popup when the onmouseover
event is fired and will stay open as long as the mouse is over the item that threw the onmouseover
event OR if the mouse is moved into the bubble. My bubble will need to have all manners of HTML and styling including hyperlinks, images, etc.
I've basically accomplished this by writing about 200 lines of ugly JavaScript but I would really like to find a jQuery plugin or some other way to clean this up a bit.
Qtip is the best one I've seen. It's MIT licensed, beautiful, has all the configuration you need.
My favorite lightweight option is tipsy. Also MIT licensed. It inspired Bootstrap's tooltip plugin.
