title: Required fieldset html [Angular]
body: <p>There is a way to required form fieldset and don't every input? </p>
  
  <p><strong>My point:</strong> the user can choose what to fill but will not have to fill all of the fieldset inputs</p>
  
  <p>I have this two:</p>
  
  <p><strong>1:</strong> </p>
  
  <pre><code>&lt;fieldset&gt;
    &lt;legend&gt; legend &lt;/legend&gt;
    &lt;label for="id"&gt; label &lt;/label&gt;
    &lt;input type="text" id="id" name="name"&gt;
    &lt;label for="id2"&gt; label &lt;/label&gt;
    &lt;input type="text" id="id2" name="name2"&gt;
  &lt;/fieldset&gt;
  </code></pre>
  
  <p><strong>2:</strong> </p>
  
  <pre><code>&lt;fieldset&gt;
    &lt;legend&gt; legend &lt;/legend&gt;
    &lt;label for="id"&gt; label &lt;/label&gt;
    &lt;input type="radio" id="id" name="name"&gt;
    &lt;label for="id2"&gt; label &lt;/label&gt;
    &lt;input type="radio" id="id2" name="name"&gt;
  &lt;/fieldset&gt;
  </code></pre>
  
  <p>I use <strong>Angular</strong> if it can be simplest.</p>
