Il faut que programme en ajax.
Ca peut paraitre un compliquer au premier abord mais c'est pas bien dur.
Voila un petit exemple qui te permet de synchroniser une liste.
re
<?php
$num=$_GET["num"];
$idc=mysql_connect("localhost","root","");
mysql_select_db("test_ajax",$idc);
$sql="select * from t2 where num_pers=".$num;
$rs=mysql_query($sql,$idc);
print("<SELECT NAME=\"zl2\" SIZE=\"5\">");
while($lg=mysql_fetch_assoc($rs))
{
print ("<option value=\"".$lg["num"]."\">".$lg["v"]."</option>\n");
}
print("</SELECT>");
?>
<script language="javascript">
var httpRequest;
function recup_data()
{
if (httpRequest.readyState == 4 && httpRequest.status == 200)
{
zl.innerHTML=httpRequest.responseText;
}
}
function synchro_lst()
