I cannot figure this out. There seems to be no checkbox or anything similar in function to add the newly created custom post type archive page into the menu.
Also the link must be active, if you are on the page. This probably isn't possible, but is there some plugin for it? For the love of me, I cannot find it :(
It is surprising that such important function isn't highlighted or easy to find. As most of stuff will be custom post type. In my case 90% of my site will use custom post types, and if I'm missing 90% of my links or they won't work like they should.. then that's a very huge problem.
