Responses were, so far: *) hook_signal *) hook_menu into more than menu (maybe) *) MVC / RoR routers (I can not care less) *) callbacks (please, not yet! One issue at one time) Some useful answers and my responses a) look at user_menu (newmenu.patch in my sandbox). I handle TRUE, FALSE, and complex stuff there, the latter with moving it to its own little helper functions. b) More than six parts will not work on neither end. The builder will not store more than six parts. The handler will make an argument out of the 7th and onwards. So, you need to write an ugly page controller if you really insist on more than six depth. But, if you ever do that please email me the site URL so I can keep away :P Could you all *PLEASE* peek in my sandbox, read the code (test.php menu_creator.php and newmenu.patch) and my post and react accordingly ON TOPIC? Thanks NK
