[wp-hackers] Custom Post Types in the WordPress Navigation Menu

[Aero Maxx]

Hello can someone help me out by pointing me in the right direction as 
to where I can find out how to add a drop down menu to a theme with my 
custom post types stored within in, have been looking/searching google 
for "custom post types in wp_nav_menu", "custom post types in 
wp_list_pages", "custom post types in wordpress themes", "custom post 
types in wordpress theme", and have drawn a blank so far, I have managed 
to find out how to get my posts in the custom post types to appear in 
with the normal blog posts, but as I will have several posts in the 
custom post types more than what would be in the normal blog, would make 
this diluted and I would therefore like to have them in a drop down box 
in the menu.

The menu on this website here http://justintadlock.com/ the "Writing" 
part on the menu I presume that these are custom post types, but I wish 
to have the menu on my site like this menu, if anyone can point me in 
the right direction as to how to achieve this, be is something on the 
codex, a blog post or something like this I would very much appreciate 
anything anyone would be able to tell me.
