Current implementation of ContentSubApps open a dialog to edit the items, e.g. editing a contact in the contacts app. There is currently no detailed view of such an item.

Editing an item in ContentSubApps should open in a tab (new SubApp) inside the app. You should be able to toggle between a preview and the editing form of an item inside the tab.

This behavior is much like the current pages app is working when dealing with the page editor.

During Sprint 8 we were able to simplify the App Framework, according to this document:

Concept - App Framework and Sub Apps

Further planned steps can be found here:

Concept - App Configuration and Naming

We need to create views similar to how we build forms with FieldBuilders:

Concept - Form and FormBuilder


Extend App Framework

  • Introduce AbstractItemSubApp
    • Like the AbstractContentSubapp (the list/tree/.. view of items)
    • this class takes care of the detailed views and editing of items.
    • offers two views: edit/view

Draft Diagram

Contacts App

  • should only extend AbstractItemSubApp and the rest should be configuration

Pages App

  • also extends AbstractItemSubApp
    • try to simplify the app as much as possible.


  • No labels
