need an fm for popup with a dropdown list

Hi,

In my requirement i need to provide a pop-up with an input field which provides a drop-down list.

I could achieve it by calling a screen with an input field (as list box). But i wanted to know if there is any function module providing the same functionality. i already tried with 'POPUP_GET_VALUES' but it couldn't full-fill my requirement.

Thank you,

Swetha
