Hi Santosh,

This is a very common question.
Search this, and the HTML/Javascript forum.
There are several approaches to doing this.
All have been discussed at length.

When searching, you'll probably have better luck if you use the term "select list". Combo boxes do not exist in HTML.

A term for this that I see bandied about often is "dependent dropdowns".
