Dynamically updating AEM TouchUI Select Fields
You can create an Adobe Experience Manager (AEM) 6 Touch UI component that updates a drop-down field (located in the component dialog) based on a selection of another drop-down field. For example, assume that a user selects a language code from a Language drop-down field. This results in a Country drop-down field being updated with a list of countries based on the selection of the Language drop-down field, as shown in this illustration.
