Most of the components are implemented using the Dojo framework. Many of the components are cross-platform meaning that they will exist for all types of devices, but they will look and behave differently depending on the device. Other components will only exist in a desktop or mobile version. Some components require special containers; Table column components belong in a Table container, for example, and cannot be placed anywhere else. Map markers belong in a Map marker container, List item components must be placed in a List Group container, and so forth.
The JavaScript source code of your components is not available to the developer. However, the skinning, sizing, positioning – and much more – are exposed as component properties in the Property Editor. Further manipulation of components can be achieved through your Java code. A component’s available properties are also determined by the Layout Manager of its parent container.
