Page layout in GovCMS is limited to predefined and preconfigured regions. The layout cannot be easily changed without some theme development. However, thanks to the Panelizer module in GovCMS, more complex layouts can be managed by content editors. The Panelizer module allows a content administrator to create custom layouts for multiple uses. At its core it is a drag and drop content manager that lets you visually design a layout and place content within that layout.
