Just have experienced to create single/multiple custom post type in any wordpress theme but i am looking for to gather/bind or it can say hook all custom post type in single post type.
Suppose, i have few post types like 'products' , 'news', 'movies', 'sports'.. so on and all these post types i want keep in single post type named 'all-post-types'. So when i click the 'all-post-type' it will show all these post types as submenu or as child something like appearance/settings menu in admin panel.
Any idea please ??
