<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>

<script>      $(document).ready(function(){

   $('.markdown-block .sqs-block-content h3').css('cursor','pointer');

   $(".markdown-block .sqs-block-content h3").nextUntil("h3").slideToggle();

   $(".markdown-block .sqs-block-content h3").click(function() {$(this).nextUntil("h3").slideToggle();});

   });    </script>
