Bootstrap Multicolumn menu

I'm trying to replace the default Autonav menu in the Elemental Theme with some menus that I found in Internet which use Bootstrap or Jquery, but I have some problems, especially when I try to use them on a mobile device.
Is it possible to trasform the Autonav menu provided by the Elemental theme in a multicoloumn dropdown menu?
