preselected values in jquery multiselect with angularjs using ng-options

Question

Jquery multiselect runs perfectly with ng-option. See below for my HTML, Directive and controller.

 <select multiselect multiple ng-model="sched.select"  style="width:130px;" 
 ng-options="option.name for option in availableOptions track by option.value" >


.directive('multiselect', function ($timeout) {
return {
    restrict: 'A',
    scope: {
        model: '='
    },
    transclude: true,
    require: 'ngModel',
    link: function (scope, element, attrs, controller, transclude) {
        $timeout(function() {
            transclude(function (clone) {
                element.append(clone);
                $(element).multiselect();
            });
        });
    }
}
});

 .controller('CreateSubject', function ($scope, factory, $cookieStore,     
 $location, $rootScope){
 $scope.availableOptions = [
 {value: "M", name: 'Monday'},
 {value: "T", name: 'Tuesday'},
 {value: "W", name: 'Wednesday'},
 {value: "Th", name: 'Thursday'},
 {value: "F", name: 'Friday'},
 {value: "S", name: 'Saturday'}    
];
});

Now my problem is how to preselect values in this scenario? I already tried this solution JQuery multiselect - Set a value as selected in the multiselect dropdown but it give me an error.

You can try by initilaze in your controller and use option.name as option.name in your select tag and no need to use track by.

in your controller:

.controller('CreateSubject', function ($scope){
 $scope.availableOptions = [
     {value: "M", name: 'Monday'},
     {value: "T", name: 'Tuesday'},
     {value: "W", name: 'Wednesday'},
     {value: "Th", name: 'Thursday'},
     {value: "F", name: 'Friday'},
     {value: "S", name: 'Saturday'}    
  ];
  $scope.sched = {};
  $scope.sched.select =[$scope.availableOptions[0].name,$scope.availableOptions[1].name]
;});

and HTML:

<select multiselect multiple ng-model="sched.select"  style="width:130px;" 
         ng-options="option.name as option.name for option in availableOptions" >

    </select>

NB. you should use option.value as option.name if you want to set value as M, T as a selected value.

and file loading order need to follow jquery, bootstrap(css, js), angular, bootstrap-multiselect (js, css), your script file

it may help you.
