Popup as a Search help

Hi ,

I need to develop one popup. and this popup should be attached a search help to one of the inputfield.

Actually i can go for freely programmed sh for this but i should use only popup to get the standard look and feel of window.

I have created a popup but dont know how to attach this popup as a search help for inputfield.

Could anybody suggest me on this...?

Thanks & Regards
