controller:

function ($scope, $mdsidenav, $mdutil, $location, invoice) {        $scope.demo = {         topdirections: ['left', 'up'],         bottomdirections: ['down', 'right'],          isopen: false,          availablemodes: ['md-fling', 'md-scale'],         selectedmode: 'md-fling',          availabledirections: ['up', 'down', 'left', 'right'],         selecteddirection: 'left'       };     }]);

whether md fab dial open depends on 'demo.isopen' model. can decide use ng-mouseenter or ng-click.
