To enable the Folding Effect, simply drag the "Foldable Elements" onto your page. Next you will have to enable the option to add an ID attribute to your elements by going to Settings->General. You will now have access to the foldable actions within your workflows under element actions. You can trigger a folding effect within your workflow, by specifying the Element ID of the element for which you want the effect to be applied as well as the folding angle. Don't forget to add the same Element ID within the Element Inspector for the Element which should be targeted by the folding effect. Groups and Images are most suited as Foldable Elements.
