Sections contain individual Element instances that are rendered by MonoTouch.Dialog
Sections are used to group elements in the screen and they are the only valid direct child of the RootElement. Sections can contain any of the standard elements, including new RootElements. RootElements embedded in a section are used to navigate to a new deeper level. You can assign a header and a footer either as strings (Header and Footer) properties, or as UIViews to be shown (HeaderView and FooterView). Internally this uses the same storage, so you can only show one or the other.
