==Introduction {{Version/WinXSince|5.1.0.0}} {{Version/MobileSince|5.1.0.0}}==If an Active List is defined on a [[Instance|Content Object]] that is associated with an [[MetaProperty#Integer|integer]] [[MetaProperty]], the property is displayed using the existing icon (the same icon applied to properties with a [[UBIK WinX Client Basics#Selective List Properties|SelectiveList]]), followed by the property's display string and the label of the currently selected list item in a closed drop-down component. An ActiveList (i.e., if it has been configured on the server for the a content object) always takes precedence over a MetaProperty SelectiveList .
For editing, it behaves exactly the same as with a standard SelectiveList. The client uses a dropdown menu UI component and the dropdown menu allows the user to select exactly one value from the Active List.
When the user opens the dropdownActiveList:
* 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.
=== XAML ===
To enable access to an ActiveList from XAML, a new property named SelectiveItems was added to the PropertyViewModel. This property returns the ActiveList if one is configured on the content object; otherwise, it falls back to the SelectiveList defined on the MetaProperty if no ActiveList is available for the content object. Below is an example of how this can be implemented in XAML. For the SelectedItem, it is important to use the PropertyValueToSelectiveItem converter and pass the control’s own ItemsSource path as the ConverterParameter, so that the list can be provided to the converter. This means that no DataTriggers or similar mechanisms are required to switch between ActiveLists and MetaProperty SelectiveLists or to perform any checks.
