You can use the AutoComplete widget to achieve this, it supports templates for results, allowing you to combine multiple attributes for display.
Make sure the list of possibilities you want to display in the widget is filled and you have the data source set to the right datasource. For example, you need an enumeration with multiple possible outcomes to be the datasource of said data selector, before you will see all enums underneath each other.
-is the context set well?
-is that context not empty?
After you conclusively established a positive on both, the reference selector should show all options underneath each other.
