The drop zone preview type can be used to add drop zones to the widget preview. It requires a widget property of type widgets to be able to store the information about the containing widgets. If the property has a data source, a header will be shown inside the dropzone containing information about the data source. This header is optional and can be hidden by setting showDataSourceHeader to false.
