Editor widget with configurations
This sample demonstrates how to add an Editor widget to a web application. It also demonstrates the use of various editor configurations, particularly restricting editing capabilities via the Editor's layerInfos property and working with FeatureTemplate grouping.
For a more basic sample, see Edit features with the Editor widget.
How it works
The widget automatically recognizes if there are any editable feature layer(s) within the map. If there are available layers, they will display within the widget. Based on the editing functionality set on the feature layer, you can update
and/or create
new features. These two workflows can be adjusted to what is needed within the application. For example, let's say you have a feature layer that has full editing capabilities set on it. But for one specific application, you may not need or want the editor to create any new features. You can restrict this by setting add
in the layerInfos property. This will disable feature creation.
In addition to this, it is also possible to limit what fields are displayed and how you wish to display them. You can do this by setting each layer's layerInfo. This takes the layer and a form template with an array of field elements. These field elements specify what values should be updated by the Editor
. This sample makes use of this since there are only a few attribute fields that need to be updated.
Starting at version 4.23, the Editor automatically includes SnappingControls. It is no longer necessary to manually add snapping via the Editor's API.
For additional information on these Editor updates and any limitations, please refer to the Editor API reference documentation.
The Editor widget encapsulates the functionality seen in the FeatureTemplates, FeatureForm widgets, and SketchViewModel. It is possible to customize some of these widgets' properties by setting the supportingWidgetDefaults property. In addition to customizing how the fields display within the Editor, you can also customize how the default FeatureTemplates display. By default, the Editor widget shows all the layers' templates in one group. To make it easier to distinguish, this sample makes use of a custom function created to help group these templates. In this example, the default behavior of the FeatureTemplates widget is customized to work with this custom grouping function.
Like other widgets, the Editor
widget uses the same type of coding pattern, i.e. you must set the view referenced by the widget. After this, the other properties can be set as the application's requirements dictate.
