I know, I have seen it before, but can not find it.

I want to make something like DropList, but to be dynamic.
When I step into edit field and start typing, I would like to see a  
"subset"
of options in "drop list". And select one option, with mouse or up-down  
keys.

So with every character entered, there would be less and less items in  
"drop down".

Anybody got some sample?

Thx, Jure
