I've seen sites that have used this technique with non adsense ads and admittedly, it was effective at getting me to notice the ad.
Anybody have good or bad experience with this technique?
If you think your intended behavior is Adsense-neutral, I would definitely ask Google before attempting to implement it.
Site and Ad Behavior
"AdSense participants are not allowed to alter any portion of the code or change the behavior, targeting, or delivery of ads."
Ad Placement
"Elements on a page must not obscure any portion of the ads."
Even though it doesn't say "you shall not delay the display of the ad by using a collapsible DIV" I personally wouldn't take a chance.
Of course, as the previous poster mentioned, you could ask AdSense tech support.
I emailed AdSense support about this about one year ago and they had no problems with it. Because your situation is slightly different, my advice would be to send them an email. My experience is that you will have a reply within a day or so.
