How to disable a <option> of select element when using AngularJS ng-options?

angularjs, angularjs-directive, ng-options

Solution

One way to do this is, to forget using `ng-options` on the `select` element, and add the options in with `ng-repeat`, then you can add a `ng-disabled` check on each `option`.

http://jsfiddle.net/97LP2/

<div ng-app="myapp">
    <form ng-controller="ctrl">
        <select id="t1" ng-model="curval">
            <option ng-repeat="i in options" value="{{i}}" ng-disabled="disabled[i]">{{i}}</option>
        </select>
        <button ng-click="disabled[curval]=true">disable</button>
    </form>
</div>

a minimal controller for testing:

angular.module('myapp',[]).controller("ctrl", function($scope){
    $scope.options=['test1','test2','test3','test4','test5'];
    $scope.disabled={};
})

Problem

Is there a way to disable an `option` in a `select` element when we populate `options` with ng-options in AngularJS? Like this: http://www.w3schools.com/tags/att_option_disabled.asp You can do it by adding `ng-disabled` to each `<option>` tag, but is there a way to do it if we are using the `ng-options` directive in the `select` tag?
