Using Granite DataSource objects to populate AEM Touch UI objects
You can create an Adobe Experience Manager (AEM) 6 Touch UI component that contains drop-down controls that can be used within the AEM Touch UI view. A drop-down control can be populated by using a com.adobe.granite.ui.components.ds.DataSourceobject. For information, see DataSource.
Once you create a DataSource object, its data can be used to dynamically populate a drop-down control, as shown in this illustration.
