I did something like this before. I used the JS form submit function when the select/option choice changed. I'm not a big fan of JS, but I feel better about it now. However, I also put a submit button next to the pull down that can be auomaticall refreshed. I made it hidden (stylesheet no display, form item disabled in case stylesheets are disabled). It says something like "refresh choices". And then I had to have logic in my CGI to detect that the choices in the box are not the correct choices for the value in the superior box (the one that, being changed should have caused the subordinate to update). Basically I had to work out a way to prompt the user to do the right thing if the automatic processing is disabled. Some people don't care too much about this. Especially if it's a corporate environment and you can dictate standards. But, on the extranet some people think it's important to fall back like this. I also considered using an "iframe" (inline frame). You can update those independent of the entire page. But, it seemed ugly.
