TYPE_AHEAD that activates after few characters are types

I need to implement a functionality in TYPE_AHEAD field where the result list appears only after a user types several characters into the box. At the moment the result list appears immediately when the field is given focus.

Please advise, thank you.

Have a look at the key listener plugin on ServoyForge:

It doesn’t seem to work in Web Client. Any suggestions?
