Number of items the user can select. Valid values include 0 (zero or one), 1 (one), 2 (zero or more), and 3 (one or more).
A single-selection tree control has a scalar data type, and a multiple-selection tree control has an array data type. If you set this property for a single-selection tree control to a value of 2 or 3, LabVIEW returns an error because LabVIEW cannot change the data type from scalar to array at run time.
This property is similar to the Selection Mode item on the shortcut menu of a tree control.
