Hi Jonathan,
Sorry, at the time of the Layout maker I was still mainly using the HTML Editor. I'm afraid I'm not too well acquainted with Coffeegrinder to be of any help with a menu for it, at least not the kind of menu you wanted.
If you stay in the Coffeegrinder system, I'm afraid you will be missing out on several new and better ways of doing things. What I would recommend is, use Site Designer and convert your sites. You can then choose between Bootstrap, Foundation or Materialize, and from then on, you can use the components available for the system you have chosen. If you are a subscriber to the CC newsletter, you should have got, in the latest one, a tutorial for creating the same kind of menu that I have for Foundation, but in Bootstrap. I haven't got around to making one myself for my sharing folder yet, although I have followed that tutorial, and it isn't at all difficult. And as always: Just holler if you get stuck!
Just one very important hint: Before you convert your sites to any other framework, make a SAFETY BACKUP!
