When using the Items From a Static List, the ‘Value’ is used as the display value and the ‘Name’ is used as the value property (which will map to the object bound the the single select). I’ve attached a screenshot that shows a configuration that should get the results you want.
Also, something to keep in mind: the Data Mapping configuration only applies when the Item Lookup Mode is ‘Items from Service’. This configuration is helpful if your lookup service is a complex object and you want to specify which parameters are used as the display and the value property.
Finally, be sure to check out our SPARK Controls page for all the details you need about all the SPARK UI Toolkit Controls. If you’d like more information about configuration options for the Single Select control, the Single Select control article referenced on that page should be useful!
