Stickify jQuery UI plugin
by Andrew Kim
This plugin turns a div into a sticky div. When a user scrolls past this sticky div, it will float above scrolling content so it always stays in the page view.
An example would be the toolbar in gmail.
Usage:
$("#divid").stickify();
$("#divid").stickify({offset: 200}); // if you want to offset the point of sticking
Depends on:
jquery 1.6.2
jqueryui/1.8.14
