Hi @91fidji
Do you want to save any data from the form? If you don’t need to save any data to your database, then you don’t need to use acf_form() at all.
You can create the select box by using the HTML select tag and set the options from the returned names (unfortunately, I’m not sure how you get names).
To redirect the user, please check wp_redirect() function.
I hope this makes sense 🙂
