I'm using the CJuiAutoComplete widget for autocomplete user entries inside a form.
Therefore I have a list with some cities. Is it possible to show only values, where the entry matches from the beginnig of the word?

An example:
When typing "ha" inside the field I get

* Ahausen
* Badenhausen
* Bremerhaven
* ...

But I need something like this:
 - Hagen
 - Hannover
 - Halle
 - ...

Is this possible?
