Example code

//Drag Rightvar 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' );            }        });}
