Example code

//Drag Right
var dragright= Hammer( document.getElementById("touch-dragright") );
	dragright.on("dragright", function(event) {
	if((event.gesture.deltaY<=5 && event.gesture.deltaY>=-5) && event.gesture.deltaX <-100){
		$('nav#menu').trigger( 'open.mm' );
	}
});

Or you can use in all pages action( #wrapper )

var touchWrapper=document.getElementById("wrapper");
if(touchWrapper){
	var wrapper= Hammer( touchWrapper );
	 wrapper.on("dragright", function(event) {	// hold , tap, doubletap ,dragright ,swipe, swipeup, swipedown, swipeleft, swiperight
		if((event.gesture.deltaY<=7 && event.gesture.deltaY>=-7) && event.gesture.deltaX >100){
			$('nav#menu').trigger( 'open.mm' );
		}
	 });
	 wrapper.on("dragleft", function(event) {
		if((event.gesture.deltaY<=5 && event.gesture.deltaY>=-5) && event.gesture.deltaX <-100){
			$('nav#contact-right').trigger( 'open.mm' );
		}
	 });
}
