Use a separate form in Jquery step

Question

I want to use a form inside the jquery-step,But when I do thisو The step is completely lost;

<form action="#" id="form1" method="post" class="validation-wizard wizard-circle" enctype="multipart/form-data">
   <form id="trp-form">
     <input type="hidden" value="trp" name="mode">                                                  

How do I solve this problem?

I want to insert an uploader that has a form inside it into a jquery-step
