 * `string | boolean`:  **showLabel** - If label should be showed
 * `boolean`:  **labelHidden** - Hide label and maintain label area
 * `string | DisplayValueType`:  **nestedViewerType** - Nested viewer type for property viewer
 * `CollectionType`: **collectionType** - Collection type for the property to be displayed (Array\None)
 * `string` : **propertyIconClass** - icon class to appear to the left of the label text.
 * *                                  The first use case was to identify Custom Properties of an Entity. [Optional].
