If an Active List is defined on a [[Instance|Content Object]] that is associated with an [[MetaProperty#Integer|integer]] [[MetaProperty]], the property is displayed like a usual [[UBIK WinX Client Basics#Selective List Properties|SelectiveList]]. An ActiveList (i.e., if it has been configured on the server for a content object) always takes precedence over a MetaProperty SelectiveList. For editing, it behaves exactly the same as with a standard SelectiveList.
When the user opens an ActiveList:
* All available options from the ActiveList are displayed as text labels.
* The label for each option is shown in the language configured on the web service. If a translation for the configured language is unavailable, the label is displayed in the default language.
* Each option in the ActiveList has an associated unique integer value that is set to the MetaProperty when selected.
* Only one option can be selected at a time. Selecting an option updates the MetaProperty value immediately.
Sorting of items in the dropdown:
* If all options in the ActiveList have unique sort order values, they are displayed in ascending order of these sort order values.
* If sort orders are not unique, options with the same sort order are sorted in ascending order by their label.
{{Hint|There are no visible differences in the UI between an ActiveList and a MetaProperty SelectiveList.}}
