Unfold to the Max

Introducing jQuery Unfold. Now you can do fancy Mail app style unfold effects in your browser. It looks great in Webkit and pretty good in Firefox (seems to be the new status quo).

Unfold Some Content

$(window).load(function() {

Note the use of $(window).load. The content needs to be loaded before calculating heights.

Collapse it


Some Options

Pass in a custom easing function to impress the girls:

  easing: 'easingFunction',
  duration: 1000,
  slices: 10 


  • Make sure all content is loaded before invoking otherwise measurements will be off!
  • Inspired by the Mail app expando transition in
  • Works in FF10+ and Webkit.
