I have been looking hard for examples but could not find anything at all. The only thing I know is that I could use the http module to get my data. Here is what I am current

<select name="selectedFacilityId" ng-model="selectedFacilityId">
         <option ng-repeat="facility in facilities" value="{{facility.id}}">{{facility.name}}</option>
     </select>

This is an example on how to use it.

The proper way to do it is using the ng-options directive. The HTML would look like this.

<select ng-model="selectedTestAccount" 
        ng-options="item.Id as item.Name for item in testAccounts">
    <option value="">Select Account</option>
</select>

JavaScript:

angular.module('test', []).controller('DemoCtrl', function ($scope, $http) {
    $scope.selectedTestAccount = null;
    $scope.testAccounts = [];

    $http({
            method: 'GET',
            url: '/Admin/GetTestAccounts',
            data: { applicationId: 3 }
        }).success(function (result) {
        $scope.testAccounts = result;
    });
});

You'll also need to ensure angular is run on your html and that your module is loaded.

<html ng-app="test">
    <body ng-controller="DemoCtrl">
    ....
    </body>
</html>

In my Angular Bootstrap dropdowns I initialize the JSON Array (vm.zoneDropdown) with ng-init (you can also have ng-init inside the directive template) and I pass the Array in a custom src attribute

<custom-dropdown control-id="zone" label="Zona" model="vm.form.zone" src="vm.zoneDropdown"
                         ng-init="vm.getZoneDropdownSrc()" is-required="true" form="farmaciaForm" css-class="custom-dropdown col-md-3"></custom-dropdown>

Inside the controller:

vm.zoneDropdown = [];
vm.getZoneDropdownSrc = function () {
    vm.zoneDropdown = $customService.getZone();
}

And inside the customDropdown directive template(note that this is only one part of the bootstrap dropdown):

<ul class="uib-dropdown-menu" role="menu" aria-labelledby="btn-append-to-body">
    <li role="menuitem" ng-repeat="dropdownItem in vm.src" ng-click="vm.setValue(dropdownItem)">
        <a ng-click="vm.preventDefault($event)" href="##">{{dropdownItem.text}}</a>
    </li>
</ul>
