slideup and slidedown with damper effect

Question

Is there a jQuery add on that has slideUp and slideDown effects with damper effect? That is, the change of size starts with a rather quick speed, and slows down towards the end of the movement.

Answer 1

You can pass in an easing to use as a second argument...

$("#something").slideDown(500, "linear");

jQuery includes swing and linear, with the former being the default.

To get the behaviour you describe, use easeOut, which is available in jQuery UI (which you've tagged the question).
