I have a validation on a cell which is bringing a list of code numbers. At
the same time in the same cell, I will like the names related to this codes
to show for users to be able to identify the name of these codes. How can I
do this?

Example:

List of codes Name of codes
15 Human Resource
33 Training

On the validation cell right now the list of codes is showing up, I want to
have the name of these codes showing as well when people are choosing the
code.
