hi!
I would like to know if there is a way to update a href link (without page reload) when a selection is made in a drop down box/menu?

for example:
[php]<?php
echo "<select name='subcat' onchange('function to append noticia[x] to href')><option value=''>Select caterogry</option>";
while (query=true){
echo "<option selected value='$noticia[x]>$noticia[y]</option>"."<BR>";}

?> [php]
<a href= localhost/?subcat=noticia[x] /a>

note: the page is not to be reloaded nor are the drop down boxes to be reset when selection is made in menu

thanks in advance
