Hi
It is not much difficult. what u need to do is make one hash map where u store region as key. And make arraylist for cities associated with that region and set iit as a map value. Now call java script on that control. In java script u should have to find out the city list associated with selected value. Then use that list values for other dropdown list.
It will work. Let me knopw if u have any doubt.

Thank you for responding but I've some more question. Last time I thout of double drop down menu i.e to have list of regions and then list of cities with in the region but I've come to realize that there is more to do. There has to be 4 drop down lists for which the first one is the base and based on the first the second drop down list will have its data dynamically and the third one will get its data based on the second and the fourth which is the last drop down list will get its data based on the third.
Example:
1. list of countries
2. list of region
3. list of cities
4. list of street name
To make it clear, when I select a specific country I want to see list of regions within the country and then when I select a region I want to see list of cities within the region ... blahblah ..
I'm looking forward to seeing your answer.
Thank you in advance.
