title: How to add inputs to a form only with javascript
body: <p><strong>Only with Javascript</strong></p>
  
  <p>I want to create a form and, depends on your choice, you will see some fields or others.</p>
  
  <p>I thought I can do that with a <code>getElementById()</code> and using <code>innerHTML</code> to override all of the forms, however I'm searching for another way that doesn't override all the form and just add a new input</p>
