Just admiring your work on this site: http://www.visitnsw.com/
We are adopting a similar navigation system with 'mega menu' drop downs. I currently have this working within Matrix but as I'm using several listings of asset listings - listings to get it to work (to avoid hard coding and keep editable with Matrix), I was wondering if there are any alternate/more efficient ways to do this.
To explain I have the following setup:
1 asset listing for the Entire Navigation -> 5 asset listings for each navigation link -> 4 asset list for each navigation link's mega menu (20 in total)
Cheers for any wisdom.
