The most typical way of populating lists in forms is through the use of the allowedValues property. From this property, you can specify an optional list of permitted values for <Select> and <MultiSelect> elements. The value of this component is always a list and usually contains strings.
<Field name=’department’> <Display class=’Select’ action=’true’> <Property name=’title’ value=’Department’/> <Property name=’allowedValues’> <List> <String>Accounting</String> <String>Human Resources</String> <String>Sales</String> <String>Engineering</String> </List> </Property> </Display> </Field>
