- Now is OK, Avast no warning :)
- Probably one day I have to write more than is now in documenation.
Do you use only modules inside submenu items? No real submenu items?
If not, I would concern redesign your menu concept. Besides It will help you will SEO/SEF as well, becuase you will be able to have short URL alias.
Mega Menu allow you to have to two columns, so on the left you can have submenu items and on the right side a image. Then it menu items would be displayed in Mobile Menu, right now, with current structure - it seems to be not possible ;/
