Hovertext on dropdown

[NGilbert]

In short, what I am trying to do is have a drop down with numerical values, but when you hover over a value it will give you a hovertext or mouse over (whatever you call it) with more information.

Example:
An evaluation with a dropdown that would rate a product 1-5. When you hover over 1 it would say "Poor", hover over 5 it would say "Excellent".

I hope someone understands what I'm getting at and is this in any way possible?
