filter for submenu_as_parent parameter
|Reported by:||plocha||Owned by:|
This filter enables plugins to remove the menu entries which have the same target as their parents.
We could use this filter to determine whether /wp-admin/menu.php and add_submenu_page should add 'same target' submenu entries. But I think there is no need for it because some plugins manually add such submenu entries. So plugins which use this filter should remove them manually.
