true, if end-users should be able to drag this AccordionControl's elements at runtime; otherwise, false.
If the AllowElementDragging property is set to true, end-users will be able to drag both items and groups at runtime and do the following:
- re-arrange child elements within their parent group;
- create nested groups by dragging them to target parent groups;
- re-arrange root groups. To do so, drag the current group below the preceding group's header.
