Admin panel custom post type ?

Hi everybody,

My question is quite simple. I’ve got 2 custom post_type that are NOT hierachical but, i want post_type “yyy” to be reliable with post_type “xxx”.
I’ve already found a trick to save – as a postmeta – the ID of “xxx” when creating an “yyy” post_type.

Ok, Fine.

But when I go in the admin panel, “edit.php?post_type=yyy&tracker=xxx”, i’d like to display ONLY the post type that have “xxx” as post_meta.

Is there a way to do that ?

Btw, “yyy” post_type have show_in_menu set to false.

Thanks !
