Description
This sample demonstrates how FeatureTable displays attributes of a FeatureLayer.
- Shows how to edit existing attributes in the table by setting FeatureTable.editable property to true.
- Shows how to add custom functional menu items to 'Options' dropdown menu using menuFunctions property.
- How FeatureTable.refresh() method re-fetches features from the layer once the layer's definitionExpression is set.
- How to change labels and editability of a field using fieldOptions property.
- How to set interactions between the map and the table by:
- setting FeatureTable.syncSelection property to true to enable selection from the table to the map.
- implementing the layer's click logic to enable selection from the map to the table.
