How to show the fields apart from id, value in a combo when the user selects an option

Content

We have an LOV which is built on the Business Object which has additonal fields apart from id and value. When the user selects an option we want to show the additional fields (reference fields) as well in the UI for the appropriate selection (In summary, can we show multiple display fields in the UI for the selection )

Example

Assume three columns for the business objects

id, City, Famous For

-------------------------------

1 London LondonBridge

2 Tokyo FlowerGardens

3 Sydney OperaHouse

We would like the user to select the city from drop down and when the user selects it, we want to show the Famous For option under it auto selected.
