Add Link to sub menu

Question

I'm battling with a wordpress plugin and custom post type - specifically adding it to a submenu. I have checked the wordpress codex pages, namely: Custom Post Types, Roles and Capabilities and the Add Submenu Codex, which I cannot post a link to as I dont have 10 reputation.

But I'm not finding a way to do this. I assume I'm missing something simple and someone here can assist.

I have a wordpress custom post type called ns_home_page and it is setup as

register_post_type('ns_home_page',
array(
'labels' => array(
'name' => __( 'Home Page' ),
'singular_name' => __( 'Home Page' )
),
'public' => true,
'has_archive' => true,
'supports' => array( 'title', 'editor', 'thumbnail', 'revisions' ),
'show_ui' => true,
'show_in_menu' => false,
)
);

Next, I have added it by

add_action('init', array($this, 'create_homepage_items_type'));

which is calling a method in the class I have created in my plugin. This all works fine. I have added three new posts and they work 100%.

The issue is now I would like to add these to a custom menu in admin.

I have the following code for this:

$page_title = 'Ns Content';
    $menu_title = 'NS Content';
    $capability = 'manage_options';
    $menu_slug = 'ns-content';
    $capability = "manage_options";
    $function = array($this, 'display_admin');
    add_menu_page($page_title, $menu_title, $capability, $menu_slug, $function);

    $submenu_page_title = 'Ns Home Page';
    $submenu_title = 'Home Page';
    $submenu_slug = 'edit.php?post_type=ns_home_page';
    $submenu_function = 'myplugin_help';
    $capability = "publish_posts";
add_submenu_page($menu_slug, $submenu_page_title, $submenu_title, $capability, $submenu_slug, $submenu_function);

This creates a menu in my admin with the title "NS Content", and this has two submenu's, "NS Content" and "Home Page". However, the link to the Home Page content type is currently

/wp-admin/admin.php?page=edit.php?post_type=ns_home_page and in order to display my posts, I need the link to be

/wp-admin/edit.php?post_type=ns_home_page Ant idea how to set this link up correctly?

You need to register custom post type properly, once it is done, functionalities like list, add, edit, trash will be handled by WordPress automatically.
