Answer 1

mm.... i faced the same problem and couldn't solved it . i think you will have to edit the plugin .

but the issue with this is that user can enter anything that is not on the list via keyboard.

the thing is you can't disable the text field , because the auto-complete values are added according to what you type in the text field .

one possible way is you can check there are no suggestion values , in text field's on-change or on-blur function . if there are no suggestions , then you entered a wrong value . so you can give a an error message .
