* 'complete' => $scriptaculous_helper->visual_effect('highlight', 'posts', array('duration' => 0.5))) ?>

*
* This would fade the element that was dropped on the drop receiving
* element.
*
* For toggling visual effects, you can use 'toggle_appear', 'toggle_slide', and
* 'toggle_blind' which will alternate between appear/fade, slidedown/slideup, and
* blinddown/blindup respectively.
*
* You can change the behaviour with various options, see
