Use the Layout Designer to define how the properties you create using the Model Manager are displayed on the Edit Properties page in Alfresco Share.
The Layout Designer provides a simple, visual representation of your page layout in the editor using horizontal sections and vertical columns. By adding multiple sections with different column configurations you can build quite complex layouts very easily. The Layout Designer consists of a layout area in the center, the layout elements on the top, and the properties arranged vertically on the left of the layout area.
