title: Multi-forms under react-hook-form v.6 and validation with yup
body: <p>I'm trying to create a multi-form and would like to do a field validation for every single form-page before I jump to the next page with the next-button! So the next-button should be inactive until the page is filled correctly!</p>
  <p>How do I manage - to trigger a validation - if I don't leave the last field on page 1 with the tab-key - but if the &quot;next&quot;-button is clicked with the mouse?</p>
