I'm creating a web page that will have software information on: basic description, operating system, free/commercial, etc. All the content will be placed (or generated) on one page. Dropdown filters at the top of the content will allow someone to select a "filter" (i.e. Windows) and it will auto remove all content (software) that doesn't work on Mac or Linux.

I have spent hours trying to find a pre-made script (Java & PHP), but nothing is coming up in Google or my search terms suck. I even tried finding tutorials on how to create what I want to no avail.

Can anyone point me in the right direction?

In your listing page

<option value="Windows">Windows</option>
<option value="Linux">Linux</option>
</select><br />
<div class="filterResults">
<script type="text/javascript">

        var Value=$(this).val();
        $.post('filter.php', {selectedValue: Value}, function(data) {
            if(data) $('.filterResults').html(data);
            else location.reload();



In filter.php

if($_REQUEST['selectedValue']) {

    //here print the datas from database related to the selected value
    echo '<h1>'.$_REQUEST['selectedValue'].'</h1>';   

THank you for replying, but could you provide a little instructions on how to set this up becasue I have three dropdowns that I need:

 Operating System - Type  - Free/ Commercial  - RESET
        Windows        2D            Free
          Mac          3D         Commercial
         Linux       2D & 3D   Free & Commercial

I apoligize for not be specific before and relating my experience with PHP. However, an instructions would be nice and how to create a rest button sothe list will go back to it's original state.
