Documentation

So We must know the $parent_slug for adding submenu. for adding submenu to p-roduct menu in admin screen we must know the parent slug of product menu.

We can add a submenu item to the “WooCommerce” menu using “add_submenu_page” and ‘woocommerce’ for $parent_slug (using ‘admin_menu’ hook), but for Products menu ‘woocommerce’ $parent_slug can’t be used.

For adding submenu to Woocomerce product menu we have to use ‘edit.php?post_type=product’ as parent slug.

For example:

function ProductsSubPage() {
  add_submenu_page('edit.php?post_type=product','Custom Page Title','New Custom Title','edit_products','new_page_slug','ProductsSubPageCallback', 99 );
}
function  ProductsSubPageCallback() {
  echo '<div class="wrap"><h1 class="">New Custom Title</h1>';
  // add Content here
  echo '</div>';
}
add_action('admin_menu','ProductsSubPage',99);

//output
