| charts[] | An array of chart items of type WebChart available on the subtype layer. |
| disablePopup | Indicates whether a client should ignore popups defined in this layer |
| enableEditing | Indicates whether a client should allow feature editing for this layer. Applicable only if the layer has editing capability. |
| formInfo | A formInfo object defining the content of the form when you are editing a feature. |
| id | A unique identifying string for the layer. |
| layerDefinition | A layerDefinition object defining the attribute schema and drawing information for the layer. See layerDefinition properties table. |
| layerType | String indicating the layer type. Valid value of this property ArcGISFeatureLayer |
| opacity | The degree of transparency applied to the layer on the client side, where 0 is full transparency and 1 is no transparency. |
| popupInfo | A popupInfo object defining the content of popup window when you click a feature on the map. |
| showLabels | Labels will display if this property is set to true and the layer also has a labelingInfo property associated with it. This property can get stored in the web map config and in the item/data. |
| showLegend | Boolean value indicating whether to display the layer in the legend. Default value is true. |
| subtypeCode | The feature subtype code identifying the layer. Used with SubtypeGroupLayers. |

| visibility | Boolean property determining whether the layer is initially visible in the web map. |
layerDefinition properties
| Property | Details |
|---|---|
| drawingInfo.labelingInfo[] | An object defining the properties used for labeling the layer. If working with Map Image layers, this property is only applicable if the layer is enabled with dynamic layers |
| drawingInfo.renderer | An object defined which provides the symbology for the layer. If working with Map Image layers, this property is only applicable if the layer is enabled with dynamic layers |
| drawingInfo.scaleSymbols | Boolean property indicating whether symbols should stay the same size in screen units as you zoom in. A value of false means the symbols stay the same size in screen units regardless of the map scale. |
| fieldOverrides[] | The layer-specific overrides of field properties. Used by SubtypeGroupLayer to modify field information for each subtype. Any field missing from this array should be hidden. |
| maxScale | Integer property used to determine the maximum scale at which the layer is displayed. |
| minScale | Integer property used to determine the minimum scale at which the layer is displayed. |
| templates[] | A property of the layer definition when there are no types defined; otherwise, templates are defined as properties of the types. |
