The Drop Down List type is used for selecting one of the values. The set of values is configured in the variable settings.
The set of values is defined in a process or an object. If you need to use the same set of values in several objects or processes, we recommend that you use Enumerations. If you also need to be able to add or change the values of this set in Web Application, we recommend that you use an "Object" type property.
In Web Application, a Drop Down List field looks as shown in Fig. 1-3.
