On the left side of the app builder you will find a panel with the navigation tree. This tree is going to be the main way of navigating across all the metadata, and it’s formed by nodes, folders and sub-nodes that represents all the different resources of your app.
Interacting with the navigation tree
Except of the root nodes, clicking on any other node in the tree will render a view in the central panel of the builder with the details and properties belonging to that specific resource. New nodes in the tree will be created, updated or deleted automatically after creating any new resource from the central panel or after updating/deleting an already existing one.
The navigation tree has five root nodes that group all the rest of the resources:
Each one of those nodes are explained in detailed in a particular section of this documentation.
