Dropdown nav

Hey, I need to make a dropdown nav but can’t work out how to make Grav output it properly. I found this link in the forums: http://learn.getgrav.org/cookbook/dropdown-menu but its a 404…

It’s now built in to the antimatter theme:

If you want a dropdown menu in any other theme you will need to modify the theme to provide that functionality. You can use antimatter as an example of how to do that.

Thanks
