I am trying to make auto complete to select option according to input from the user

something like

  <input type=text onkeyup=findit()>

<select id="sel">
        <option value="s0001">Adams</option>
        <option value="s0002">Alder</option>
         .
         .
         .
<select>

I found this code 'but it only work on one select in the page( I need multi select)

<html>
<head>

 <script type="text/javascript">


 //initialize some global variables
var list = null;
function fillit(sel,fld) {


        var field = document.getElementById("entry");

Any Ideas How to make it work on multi select on the page?

Not sure if this would work for you, but chosen.js has a really nice autocomple multi select

http://harvesthq.github.com/chosen/

Usually Autocomplete is for single values, but the jQuery UI autocomplete does have a multiple select function. Perhaps try that? Minimum effort coding for you that way.

An odd way to do that is to change the ID in the script and copy it the number of times you want to use this options in the page. so for example:

select id="sel1"
select id="sel2"
select id="sel3"

and then. copy the script and replace every (sel) with sel1 past it again and replace (sel) with sel2 and so on. not the best solution but it will work. Good Luck
