AngularJS Validation on <select> with a prompt option

Answer 1

You can try to add form, like:

HTML

<div ng-app="myApp" ng-controller="MyCtrl">
     <form name="mainForm">
    <select name="businessprocess" ng-model="businessprocess"  required>    
        <option value="">-- Select Business Process --</option>
        <option ng-repeat="v in processes" value="{{v.id}}">{{v.value}}</option>
    </select>
    <span class="error" ng-show="mainForm.businessprocess.$error.required">required</span>
</form>
</div>

js

angular.module('myApp', []);

function MyCtrl($scope, $timeout) {
   $scope.processes = [{
        id: "C",
        value: "Process C"
    }, {
        id: "Q",
        value: "Process Q"
    }];
}
