Autocomplete Text Field like dropdown

Is there a way to make an Autocomplete text field/searchbox in a similar fashion like dropdown?
An example would be appreciated.
Alternatively how can I obtain a json output with a searchable query string?

Hi Ruggiero,
The dropdown field has an autocomplete setting which when used will make the dropdown auto complete, this is not appropriate ?

Hi Max,
sometimes it might be useful to have an autocomplete function like "google" search engine. "Dropdown" works perfectly in the case you have a compulsory choice but not in the case I want to choose another "new" option and say write/save to the DB.
I have managed to do it with textbox but had to use lot of custom code.
In other words my question is: "is there a cleaner way to do it like your dropdown autocomplete demo?

Hi Marco,
Did you try to leave the dropdown options box empty ? this does not give you the desired effect ?
There is a possibility to have a full featured auto complete search but is not implemented in Chronoforms yet!
Best regards
