I have managed to get to the stage where I need to build some dynamic relational JavaScript menus, I have the following MYSQL/PHP can anyone help me build the select menus?

Üç menüleri (Genişlikleri, Yan duvarlar ve Jant) vardır.

<?php
    $query_posts = "
        SELECT DISTINCT meta_value
        FROM $wpdb->posts as wposts, $wpdb->postmeta as wpostmeta
        WHERE 
            wposts.ID = wpostmeta.post_id 
            AND wpostmeta.meta_key = 'Product'
            AND wpostmeta.meta_value LIKE '%%%/%%/R%%'
            AND wposts.post_status = 'publish'
            AND wposts.post_type = 'post' 
        ORDER BY wposts.post_date DESC
    ";

    $result = mysql_query($query_posts) or die(mysql_error());
    $ar_widths = array();       // setup array of widths
    $ar_sidewalls = array();    // setup array of sidewalls
    $ar_rims = array();         // setup array of rims

    while($row = mysql_fetch_array($result)) {
        list($width, $sidewall, $rim) = explode("/",$row['meta_value']);
        $menu[$width][$sidewall][$rim] = 1;
    } 

    $widths = implode('","', array_keys($menu));
    print "var widths = new Array(\"$widths\", \"--\");\n";
    print "\nvar sidewalls = new Array();\n";

    foreach($menu as $width => $sidewall_array) {
        $sidewalls = implode('","', array_keys($sidewall_array));
        print "sidewalls[\"$width\"] = new Array(\"$sidewalls\", \"--\");";
        print "\nvar rims[\"$width\"] = new Array();\n";

        foreach($sidewall_array as $sidewall => $rim_array) {
            $rims = implode('","', array_keys($rim_array));
            print "rims[\"$width\"][\"$sidewall\"] = new Array(\"$rims\", \"--\");";
        }
    }
?>

PHP Output (only some of it shown here)

var sidewalls = new Array();
sidewalls["480"] = new Array("65", "--");

var rims["480"] = new Array();
rims["480"]["65"] = new Array("R28", "--");

var rims["540"] = new Array();

var rims["600"] = new Array();
