title: How to use hidden type and have a validation on radio buttons in angular js?
body: <pre><code> &lt;input type="hidden" value="{{r.radioname}}" name="{{field.Name}}" 
                    ng-model="inputfield[field.Name][r.radioname]" required&gt;
   &lt;input type="radio"   id="radio_{{$index}}"  value="{{r.radioname}}" name="{{field.Name}}" 
                    ng-model="inputfield[field.Name][r.radioname]"&gt;
   &lt;span style="width:115px;text-transform: capitalize"&gt;{{r.radioname}}&lt;/span&gt;
  </code></pre>
  
  <p>I have tried like above but its not working.I want to have the submit button disable until the radio button is selected.When i directly give required to input <code>type="radio"</code> its not working.</p>
  
  <p>So i have chosen another way by using hidden still its not working.Can any one please help me to solve this problem</p>
