charts[]	An array of chart items of type WebChart available on the footprint layer.
disablePopup	Indicates whether a client should ignore popups defined in this layer
effect	Effect provides various filter functions to achieve different visual effects similar to how image filters (photo apps) work.
enableEditing	Indicates whether a client should allow feature editing for this layer. Applicable only if the layer has editing capability.
featureEffect	Feature Effect emphasizes or deemphasizes features that satisfy a filter using graphical effects
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.
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.

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.
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.
