I am writing a portal using "Double Navigation with slim SideNav and fixed Navbar" example but would like to give users the option of having the menu on the Right.

Currently, each user can set preference for language, time zone etc that are stored in the db, and I would like to add " right or left" menu as a user preference.

Our legacy app has the menu on the right to avoid unsettling users when we upgrade, we would like to give them the option to have it on the right. Suggestions?

Thank you in advance.
