First to thanks all on replays. I knew that my solution is not perfect, and I hoped that someone will find better solution (secretly John).
@Justin We all fill the pain. My knowledge of jQuery still have boundaries, trick is to find way how to jump over it. @John, Mitch This looks and feels better than my solution. I knew that Apple use same heights, but that was "too" easy ;). Now I'll try to your accordion transform to inverted one. John, you prove me that jQuery have some secret possibilities that aren't documented (otherwise, they will not be secret :) ). One more thing: In hours of desperation, I tried to make it by mootools. I found mootools is much harder to learn. Last year I spent 3 hours from first opening of jQuery.com until I made tabbed navigation with content loaded via ajax.
