hiding an option in ng-options

angularjs, javascript

Solution

You could use a filter in the ngOptions expression:

<select ng-model="selectedValue"
        ng-options="permissionLevel.text for permissionLevel in 
                    permissionLevels | filter:shouldShow">
</select>

and define the shouldShow() function to $scope in the controller:

$scope.shouldShow = function (permissionLevel) {
  // put your authorization logic here
  return $scope.permission.canWrite || permissionLevel.value !== 'ROLE_WRITE';
}

Problem

I'm pretty new to Angular and trying the ng-options. In my controller, I have: ``` $scope.permissionLevels = [ { value: "ROLE_READ", text: "Read Only" }, { value: "ROLE_WRITE", text: "Write" } ]; ``` In my template, I have: ``` <select ng-options="permissionLevel.text for permissionLevel in permissionLevels" ng-model="selectedValue"></select> ``` Depending on the view, I want to hide either Read or Write. So in my controller, I have another flag that indicates what view it is. Before I used ng-options, I had a normal select drop down and did something like this: ``` <select> <option>Read Only </option> <option ng-show="shouldShowWrite">Write </option> </select> ``` Is there a way to do this with ng-options? Thanks.
