[Technology Preview] Pick List Manager

You can now create Pick Lists to associate with an item type property definition using the Pick List Manager. Pick lists provide a way to let you use predefined values for item types properties. You can specify a pick list for an item in the property definitions of Item Types dialog, and then specify a pick list value in the Attach Item tool for the specified pick list. Once the item is attached to an element, if needed, you can re-specify the pick list value in the Properties dialog of the element.

For example, you can create a pick list named Manufacturer with names of different companies added as pick list Values.
