I would like to menu to sandwich on mobile devices to create a mobile menu.
I followed these instructions and the menu disappears totally when viewed on a desktop. And when viewed on a mobile device 2 menus are displayed one collapsed and one expanded.
Also if I use an actual side bar the menu displays at the bottom of the page on mobile. I had to create the pages full width and use 2 columns to get the menu at the top on mobile devices. I would like to use a proper sidebar rather than columns to display the menu.
