Answer 1

You can forgo using the ng-options and use ng-repeat instead and make the first option blank. See example below.

<select size="3" ng-model="item">
    <option value="?" selected="selected"></option>
    <option ng-repeat="s in itemlist" value="{{s.value}}">{{s.name}}</option>
</select>

Answer 2

I had same problem and after a lot of googling,I understood the main issue was related to my angular version, if you use Angular 1.6.x, just use the ng-value directive and it will work as expected.

also I set an initial value in my controller, like this :

$scope.item = 0;
