Naive question about cascading menus

[Graham Samuel]

Folks, I've puzzled over the docs, but I can't understand how I can have a 
menu in a normal menu bar (not a stack menu) which can have some items that 
cascade (i.e. have submenus) and some that don't. There is a nice example 
in The Scripter's Scrapbook, where e.g. an item of the 'text'  menu 
cascades into a list of fonts, while others don't cascade. It seems from 
the docs that (a) your menu has to be a stack menu and (b) its menuMode of 
'cascade' applies to the whole menu (button), not just some items of it. 
Clearly I have missed something pretty massive. I feel dumb, but there it is.

All help gratefully received, as ever.
