title: how could I get checkbox value in email after submit from https://formsubmit.co?
body: <p>hi I use <a href="https://formsubmit.co" rel="nofollow noreferrer">https://formsubmit.co</a> as form submit.
  <br>
  I could use select and text input, but I couldn't get value from checkbox.</p>
  <pre><code> &lt;label class=&quot;container&quot; for=&quot;subscription&quot;&gt;subscription
        &lt;input
           type=&quot;checkbox&quot;
           checked=&quot;checked&quot;
           name=&quot;subscription&quot;
           value=&quot;on&quot;
           id=&quot;subscription&quot;
         /&gt;
     &lt;span class=&quot;checkmark&quot;&gt;&lt;/span&gt;
  &lt;/label&gt;
  </code></pre>
