I have indeed had a good measure of 'fun' implementing the expanded menu.
Here's a full-sized screen capture of the prototype 15-slot KBMM version of my website. As you can see, the 15 top-menu items all fit comfortably in a 1280-width. The only issue was the need to limit slot 14 to a single column (two-columns would extend beyond the right-hand limit of the 1280 area.
Given the numerous sections necessitated by the subject matter, the flexibility of KBMM (which, I readily acknowledge, I have applied very simply indeed), achieves the principal aim of a menu; which is logical, intuitive access to the content of a website. As an extension for WYSIWYG Web Builder
, KBMM is essential.
My perpetual thanks to you for taking the time to expand KBMM.
