How to see full list of multi select values (Help Desk Redwood)

Summary:

I have a created a custom multi select field in HR Help Desk Redwood and the client have asked that all the values be displayed as they wouldn't know that other values existed. Is there anyway to list all the values once the drop down is selected. I have circled where it says 'more results available' but the user will have to know what the values are in order to type them in
