Forms: Ranking choices in a question

I'm working on a survey in a form. I have a question with five choices. I want the user to be able to put them in order of importance. For example, the choices are transparency, adaptability, positive attitude, dependability, and efficiency. I want the user to put these in order of what they deem to be most important vs. lease important. What is the best way to do this? Thank you.
