Hi, I solved the problem now without jQuery. It wasn't as hard as I had expected. If anybody else ever has the same problem, a (more or less) copy&paste solution is given here [German] http://aktuell.de.selfhtml.org/artikel/javascript/draganddrop/
@Karl Sorry, I did not specify directly, but the error, though trying to use UI draggable, comes from a jQuery function (jQuery::offset) and not from an UI function. Thats why I posted it here. Anyway, the approach I posted above is pretty straightforward... I guess nearly as simple and probably faster than jQuery could archive... thx jakkob
