I want to populate a multilevel drop down. How can we use a hashmap to populate it?? I have 3 menus , the second value depends on first , and the third value depend on second value selected ?

This is a very common question, and one that has been answered many times in the HTML forum. Search for "dependent" or "cascading" dropdowns.

The short answer is to use Ajax to fetch the values of each subsequent drop down as values are selected.
