Thanks, that helped me a lot.
I would like to set car as the default selection. I can use
the :default => in options_for_select but that dooesn't seem to
trigger the observer.
I tried to add
Event.observe(window, 'load', function() {
$F('game_type').value = 'car'
});
after the selection box observer but it doesn't set the car default.
Someoene has an idea?
Thanks
