ok got this to work where it will only search the catagory that its displayed on
take this line (around 18) in includes\templates\TEMPLATE\sideboxes\ tpl_product_filter.php
$content .= zen_draw_pull_down_menu('categories_id', zen_get_categories(array(array('id' => '', 'text' => PRODUCT_FILTER_TEXT_ALL_CATEGORIES)), '0' ,'', '1'), (isset($_GET['categories_id']) ? $_GET['categories_id'] : ''), '') . zen_hide_session_id();
and replace with
$content .= zen_draw_pull_down_menu('categories_id',zen_get_categories(array(array('id' => $current_category_id, 'text' => $current_category_id)), '0' ,'', '1'),(isset($_GET['$cPath']) ? $_GET['cPath'] : ''), '') . zen_hide_session_id();
NOTE* -- If you set your catagories display to false in product_filters_define.php it WILL NOT WORK
now just to find a way to make the catagories dropdown box dissappear from the form?
