How do I make tabs inside tabs in this code?

Question

please tell me how to make tabs inside tabs in this code?

 $('.tabs-box').each(function(){ $(this).find('.tabs-sel span:first').addClass('current'); $(this).find('.tabs-b:first').addClass('visible'); }); $('.tabs-sel').delegate('span:not(.current)', 'click', function() { $(this).addClass('current').siblings().removeClass('current') .parents('.tabs-box').find('.tabs-b').hide().eq($(this).index()).fadeIn(400); }); 

 .tabs-b {display:none;} .tabs-b.visible {display:block;} .tabs-sel {padding:20px 0 0 20px;} .tabs-sel span {display:inline-block; padding:10px 20px; vertical-align:top; cursor:pointer;} .tabs-sel span.current {background-color:#4e647a;} 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="tabs-box"> <div class="tabs-sel"><span class="current">1</span><span>2</span><span>3</span></div> <div class="tabs-b visible">12</div> <div class="tabs-b">13</div> <div class="tabs-b">14</div> </div>

Try something like this in one of the sub tabs:

  <div class="tabs-b visible">
    <div class="tabs-sel">
    <span class="current">12</span>
    </div>
   </div>
