You could use Javascript to either
a) hide all select boxes except the one corresponding to the choice (by
editing the display property), and have the PHP script generate a SELECT for
each possible choice with "display: none" set by default
b) have the PHP generate a Javascript which will clear the second box and
re-fill it with the appropriate entries onChange of the first select

I think you need Javascript one way or another, if you want to get around
reloading the page (whether it be the main page or an (i)frame).
