Multiple Columns in dropdown option

[Paul_Grindley]

Hello

I have a field in my data to represent country tax code and would like to set this up as a dropdown. In the dropdown I would like to have a country description next to the tax code so users can select easily.
Country Code
United Kingdom GB
Germany DE

I created a reference table to contain values as above. Code is the unique key. Is it possible to show both values in the dropdown?

Thanks
Paul
