Selecting a predefined value
You select predefined elements' values in the form.
If a compound type is set in the Available types and two or more types with predefined elements are specified, the form will contain two tabs, Type and Value.
You can select value type on the Type tab, and select predefined element of this type on the Value tab.
If the type specified in the Available types field is not compound, or only one of the specified compound types has predefined elements, then you can select predefined elements of this type in the form.
