BetterSlide Plugin Replaces jQuery's native SlideUp/SlideDown/SlideToggle functionality to eliminate the "jump" bug. Version 1.0b Updated 2012-01-17 License: MIT (https://github.com/jquery/jquery/blob/master/MIT-LICENSE.txt) THIS PLUGIN IS IN BETA. PLEASE REPORT ALL BUGS TO ME AT tracy@taupecat.com. THANK YOU. This plugin is based on the work by Remy Sharp and Dan Switzer in identifying and building workarounds for this bug. jQuery should fix this in core, but as of jQuery 1.7.1, it still exists.

Supports any easing effect you have installed, including jQuery UI effects. callback: ''; Function to perform upon completion of the animation Alternate Usage (to more closely match native jQuery commands): $('element').betterSlideUp( { options } ); $('element').betterSlideDown( { options } ); $('element').betterSlideToggle( { options } ); The same options are recognized, except for the "action" option.
