To populate a dropdown list???

I have 2 dropdown list in my html. Is possible for me to populate the option values in the second dropdown list depend on what I select in the first one.
Thank you.

Sure just search the forum (or the web) for "javascript combobox". Here's one good link http://www.codingforums.com/showthre...cript+combobox

but there's literally thousands more.
