Abstract: User interface features for a user interface may be selected or generated based on introspection of a template. A template, such as a content item template, may include an annotation identifying a portion for which a user interface feature is to be generated. Introspection of the content item template may include determining the APIs used, the defined data types, the instantiated data objects, and/or the annotations of the template. Based on the determination, a data tree may be determined for the template. User interface features may be generated based on the values of the data tree. A user interface may be created based on the generated user interface features. In some instances, a preview of the content item may be included with the user interface. The preview may be updated as values are modified for the user interface.
