NGUI autocorrect

Hi , I wanted to have an input field which shows suggestions based on a given dictionary. It is supposed to get name of the user. But I want to show the user suggestions. For example if the user types "J" the input field shows "Jerry, John,..." based on the given dictionary. I'm working with NGUI for my UI and it is better if I can implement such feature with NGUI.

NGUI already has an "AutoCorrect" checkbox for its UIInput but I couldn't find out how to give it a dictionary.

Thanks very much
