This menu includes the fliplet-menu dependency by default, though you can safely get rid of it if you don't intend to use the default stylesheet included.
The toggle of your menu must be declared using data-fl-toggle-menu="jquerySelector" attribute. The jQuery selector will get its "active" class toggled on and off when the toggle is clicked/tapped.
You should also have at least one html tag with the data-fl-navigate-back attribute to let the user navigate back.
