2 Columns dropdown list

I would need a dropdown list with 2 columns to be displayed.
A bit more info: I have a collection with a reference field to a second collection, but in that field only numbers (even if it’s a primary text field) are displayed. So I would need a second column to be displayed in the dropdown list to display more info and so select the right value. Is this possible with code?
Thanks
