highlight menu when child is custom post type

I do have a meniu from pages with custom templates. Each of them has a

$args = array(
'post_type' => 'portfolio',
'paged' => $paged,
'portfolio-category' => 'woman',
'posts_per_page' => esc_html($portfolio_number)
);
$portfolio_query = new WP_Query($args);

Maybe I’m doing something wrong with my hierarchy, but how can I highlight the menu item when somebody views it’s custom post type by category?
I’ve googled and tried few functions, but none of them worked..
