Javascript features of a recent plone website

Description: Note: the text isn't very readable, but that's not the point of the screencast. It is all in Dutch anyway :-) Shows two javascript features of a recent Plone website that Zest software made ("docentendashboard"). First is drag-and-drop of portlets on a dashboard, done by integrating yahoo's dnd library into Plone's kss javascript framework. The second is simple interactions between checkboxes on an edit form.
