[jQuery] Autocomplete: prevent the users from entering a value outside the list of values.


Hello
We are using this in our production project
http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/
We currently maintain a list of values.
We would like to prevent the users from entering a value outside the
list of values.
The plugin has helped us avoid select and option for dropdown.
This will mimic the behaviour of select/option as a value outside the
list cannot be entered.
Example:
Cars: Audi, VW, BMW, Tesla, Ferrari
We dont want the users entering Ford
Please give some guidance.
