angular select option failures

if you strange empty options like that

<option value="? undefined:undefined ?"></option>  

probably you changed angular version and your code is not supported anymore. also if you want to create select with default value you can do it like that

<select ng-model="myModel" ng-init="myModel='default'">
  <option value="default">Select</option>
  <option value="1">Test</option>
</select>
