The plugin will support three-level admin menus once WordPress supports them. Right now WP core has a hard-coded limit of two admin menu levels (this only applies to admin menus specifically, not navigation menus and so on).
Technically it would be possible to add a third menu level with a plugin, but that would take a lot of work. You’d basically have to rebuild most of the admin menu from scratch.

Ok, thanks for the info! I’ll see if I can submit that as a suggestion or something…
I love your plugin, and are happily using the pro version.
But the missing ability to create sub-sub menus (3rd level) in WordPress backend, is becoming a real problem for me. Hasn’t there been any progress on this?
I’ve been looking into it recently. It looks like it would be possible to add 3rd level menus with JavaScript, but it would be very hard to make the implementation reliable (that is, working in all browsers and compatible with other plugins). You’d have to constantly work around existing WordPress scripts and CSS styles that were all designed under the assumption that there would only ever be two menu levels. The chances of breaking something are very high.
I’ll see if I can add an experimental, opt-in “3rd level menus” feature to the Pro version in the next few months. However, it will probably only work in desktop browsers (no mobile, at least initially), and it will be completely useless to people who disable JavaScript.
Ok, i will be happy to try it out and test it in some different sites when you have something you think works.
