Drop down for an input field in the search UIBB feeder

Hi,

How can I make one input field to Drop Down?

I have tried populating the ENUMERATION structure of the FPMGB_T_SEARCHFIELD_DESCR of the Search UIBB. This brings an F4 Search help.

However, I am looking for a simple drop down. The examples I am referring here all are corresponding to FORM UIBB and not SEARCH UIBB.

Thanks,
