Observe these three images.

zoom 100%

zoom 110%

zoom 90%

you can see it live here, just open any monthpicker dialog & perfrom zoom-in zoom-out.

My question is, what can we do, so that the monthpicker dialog will always stay attached to the input feild.

Changed

_menu.appendTo( isInline ? _el : document.body );

to

_menu.appendTo( isInline ? document.body : _el.parent());

and it worked!
