Woocommerce categories

So I got a site that run woocommerce. On the left had side it has a list of categories.

At the moment it lists all categories and also shows the count.

I want to only display categories that have products with a certain meta_value.

Any ideas how I can do that?

Thanks.

 

To make sure that you are in the product archive page, pre_get_posts action needs to be used before the loop and conditional)_tags. Also to filter the product categories a taxonomy query will be needed.
Place the following code in your plugin or theme's function.php file:

add_action('pre_get_posts','shop_filter_cat');

function shop_filter_cat($query) {
    if (!is_admin() && is_post_type_archive( 'product' ) && $query->is_main_query()) {
       $query->set('tax_query', array(
                    array ('taxonomy' => 'product_cat',
                                       'field' => 'slug',
                                        'terms' => 'type-1'
                                 )
                     )
       );  
    }
}
