Persistence Custom Field

Greeting, IFS Community.

Following the creation of a CLU with four fields and the creation of a custom persistance field using

the CLU created as a reference.

The custom field has the following properties:

              Insertable, Updatable, Searchable, List of Value

In contrast, when I try to search populate data using the list of values, the field displays only one field, rather than the four from the CLU. 

What is the best way to make the other 3 fields visible in my search box from the List of Values (LV)?

Is there a way to make the other three fields visible from my CLU?

Thanks,

JL
