Is it possible to specify a hierarchy of menu-item options in racket/gui more than 2 deep?

In other words, I am able to define menu-item options such that I do get a menu-bar with options that present sub options and I can call functions using 'callback' from those suboptions, but I have thus far not been successful at creating a deeper hierarchy of subsuboptions.

Here is an example in a gist: https://gist.github.com/SimonLSchlee/e496830a7872e224b7afbd4fa6ef5fd8

You can't create a hierarchy of menu-items%, because menu-items are always leaf nodes (a "terminating" node in the hierarchy).

But you can have many nested menu% elements which can have menu-item% as children wherever you want to be a clickable item, instead of another sub menu.
