First, you need to use JavaScript (I think the onchange handler) to 
automatically submit the form when the user selects an option from the 
dropdown list.  That's no big deal.

But to maintain the querystring, you will need to do a bit of 
finagling -- but it's nothing hard.  You could either use 
$_SERVER['QUERYSTRING'] and place the value of this variable into a 
hidden form field, or you could do a foreach ($_GET) and concatenate the 
results into a string and place that into a hidden form field.

If you aren't sure what I'm talking about I can write up an example.
