Widget areas on Hierarchical Custom Post Type

Hi. I tried to add support for my custom post type “obchod”.

So I added this code into my functions.php file in my theme.

add_post_type_support( ‘obchod’, ‘woosidebars’ );

It works well but only when custom post type is not “Hierarchical”.

When custom post type is “Hierarchical” the checkmarks on the post type’s “list” don’t show up.

Can you fix it please, so that will work also for “Hierarchical” custom post type?

Thank you, David
