Populate controls based on dropdown

I have a drop down that pulls data (ADO) when the page loads.

I want to make a selection on this drop down and populate the other
controls on the page based on the selection.

I want to do this without reloading (submitting) the whole page.

How do i do this?

W3C DOM:
createElement
<http://www.mozilla.org/docs/dom/domref/dom_doc_ref46.html>,
setAttribute
<http://www.mozilla.org/docs/dom/domref/dom_el_ref57.html>, and
appendChild <http://www.mozilla.org/docs/dom/domref/dom_el_ref32.html>
are probably your best bets. Since I don't know what you want to do
really, I can't give an example with a definitive answer (this is how
to do what you want...).
