I'd like to show a form view when an item in a list is tapped, but its not clear to me what the best method of achieving this is. I've not found a rich enough example to figure out the best practice. A NestedList seems easiest to achieve the change of view but the model I need to show in the list view is more suited to a List rather than a NestedList model.
Don't know if it's what you want but you can try Ext.NavigationView. You can build your different items and then with push() and pop() you can realize the navigation
