Add class to slicknav_menu div

[kappaluppa]

I'm using slicknav for multiple menus on the same page. Currently I'm theming them using nth-of-type().

I'd like to "stack" the slicknav menus. I'm thinking that an additional class would allow me to prepend one slicknav to another. Perhaps using the label as a class?

If I had

slicknav_menu.first
slicknav_menu.second
slicknav_menu.last

I could do prependTo:'.slicknav_menu.last'

Thanks! K
