Сквозной фильтр по сайту = категория+производитель+цены
Здравствуйте!
Помогите с реализацией фильтра.
Не получается реализовать фильтр, который бы включал в себя выпадающий список категорий верхнего уровня магазина+ ко всему к этому нужно чтобы он был виден на всех страницах.

На данный момент в основном макете прописал
<?php
   $Shop = & singleton('shop';
   $param['xml_show_all_producers'] = true;
   $param['xml_show_all_sellers'] = true;
   $Shop->showshop(1, 'Фильтр', $param);
?>   


а xsl такой:
<?xml version="1.0" encoding="utf-8"?>
