Takayuki Miyoshi on "[Plugin: Contact Form 7] dropdown form"

Complete newbie here. I have a list of athlete results that I set up in Advanced Custom Fields (ACF) and I would like to sort the list of results by athlete name. How would I go about setting up the dropdown list with Contact Form 7? The page is at:

results here

Any help would be greatly appreciated.
Thank you in advance.

Do you have any reason you want to do this with Contact Form 7? I think this task is what ACF is better to handle.
