[parthnayak7448]

Even after using menu-state value closed in controller it is not closing menu on click
<nav mfb-menu menu-state="close" position="br" effect="zoomin" label="Select" active-icon="ion-edit" resting-icon="ion-plus-round" toggling-method="click"> <button menu-state="close" mfb-button icon="ion-clipboard" label="New Issue" ng-click="newOcc()"></button> <button menu-state="close" mfb-button icon="ion-document-text" label="New Event" ng-click="newEvent()"></button> </nav>

In controller
$scope.close = "closed";
