Compare: http://openrico.org/demos?demo=accordion (based on Prototype)
To: http://jquery.bassistance.de/accordion/?p=1.1.2.5 (based on jQuery) You'll notice the Prototype version does not bounce at all. The jQuery version does. Yes you can set a height so it doesn't effect the rest of the page, however you'll still see the accordion itself bounce. It does this with every effect that toggles the height and I haven't seen one accordion plugin using jQuery that doesn't bounce. If you just use Show and Hide, you won't see the bump, but then you lose the slide effect. It seems like a small issue, but in every project, i've had to revert to the Prototype version because the client didn't approve of this small bumping issue. The apple site also has a good example of a smooth accordion effect. Any ideas?
