    Hello! How do I prevent the user to add any entry in a drop down field but just one of those I entered? Sorry, I meant in an autocomplete field

    You can use duplicate check or field limit feature so when the user enters the same value that's already submitted, they will not be able to proceed in submitting the form.

    Hope this helps!
