The Bootstrap Mega Menu
displays root categories or departments in a sidebar with a flexible 4-3-2-1 centered grid for subcategories displaying a column of level 3 categories with hover or click to level 4 categories with pictures (and or no. of products and description). The mobile sized multi-level sub-category menu uses jQuery toggle.
The admin configuration works in the same fashion as the Top Menu and as such requires minimal settings - any categories set to be included in the Top Menu are displayed. The About dropdown is displayed by default, but can be easily updated to a home link or dropdown with navigation anchors.
Topics are set by using the include in Top Menu option.
My cart includes all the links as found in Customer Navigation.
Easy to install, the Bootstrap mega mega menu is a simple and effective upgrade to your nopcommerce powered website.
