This term applies to the views that you can build using advanced XML with the Module System.
A view temlate provides the structure and layout to the dashboards and views that you build with the Module System. There are two types of view templates: dashboard and search. When you build a view using advanced XML, you first specify the view template type. As you build your view, use layout panels or panel types specific to that view template type.
