Want to display selected category in dropdown

Hello
Yes, exuding in drop-down doesn work for subcategories – it is a bug! You can easy fix it, I did it already for the next version but its still beta:

* open wp-content\plugins\woocommerce-products-filter\views\html_types\select.php
* find function woof_draw_select_childs
* before

$childs = apply_filters('woof_sort_terms_before_out', $childs, 'select');

add

//excluding hidden terms
        $hidden_terms = array();
        if (isset($WOOF->settings['excluded_terms'][$tax_slug]))
        {
            $hidden_terms = explode(',', $WOOF->settings['excluded_terms'][$tax_slug]);
        }

then after

if ($_REQUEST['hide_terms_count_txt'])
            {
                $count_string = "";
            }

drop next code

//excluding hidden terms
            if (in_array($term['term_id'], $hidden_terms))
            {
                continue;
            }
