gistfile1.js

app.controller('myController', function($scope){
   $scope.teams = [
      {id:1, name:'team 1'},
      {id:2, name:'team 2'},
      {id:3, name:'team 3'}];
    
    // if I want to preselect item I can do following
    // $scope.myTeam = 1;
});

gistfile2.html

<select ng-options="team.id as team.text for team in teams" name="teamOption" ng-model="myTeam" class="InputBox">
  <option style="display:none" value="">Select a team</option>
</select>
