You don't necessarily need JavaScript for this:
<?
if (isset($_GET) && array_key_exists("s", $_GET))
$MODE = "expanded";
else
$MODE = "normal";
// ...
if ($MODE == "normal")
{
?>
<form name="form" action="<?= $_SERVER["SCRIPT_NAME"]; ?>" method="get">
<select name="s">
<option value="yes">Yes</option>
<option value="no">No</option>
</select>
<input type="submit" value="Continue" />
</form>
<?
}
else if ($MODE == "expanded")
{
?>
<form name="form" action="nextpage.php" method="get">
<select name="s">
<option value="yes">Yes</option>
<option value="no">No</option>
</select>
<input type="text" name="foo" value="Now fill me out!" />
<input type="submit value="Next Page" />
</form>
<?
}
?>
Of course, if you want to have the dropdown selection automatically resubmit the page, without the user having to click "Continue", then you'll have to use JavaScript.
Cheers,
