The items of a dynamic selective list are instances of [[ContentClass]], also known as {{UBIK}} objects. So picking a dynamic selective list item is just like picking a query result item during editing a Guid/link property. In fact, properties having dynamic selective lists are Guid properties and the feature shares is based on the same technology as the general [[UBIK_WinX_Client_Basics#Guid_editor|Guid property editing]]. In other words:
* The items are found through a filter query (specifically a DSL_QUERY);
* The display strings of the selected item are presented as the display value of the property;
