The Experience Builder Add Data widget currently presents a service or item as a single selectable result. When an item contains multiple layers, tables, or nested group layers, users cannot easily inspect its contents before adding it to the map.
Please provide a workflow similar to the Map Viewer Add layer interface, where users can:
- Open a selected item and view its details.
- Browse its layers, tables, and group-layer hierarchy.
- View basic information for each contained layer or table.
- Add an individual layer or table instead of the entire service.
- Add a group layer together with its contained layers.
This would help users find and add only the content they need, avoiding unnecessary layers being added to the map.
