      <div data-role = "collapsibleset" data-content-theme = "a" data-iconpos = "right" id = "set">
         <div data-role = "collapsible" id = "set1" data-collapsed = "true">
            <h3>Heading 1</h3>
            <p>Hi!! This is collapsible content.</p>
         </div>
      </div>
      
      <script>
         $( document ).on( "pagecreate", function() {
            var nextId  =  1;
            $("#add_collapsible").click(function() {
               nextId++;
               var content  =  "<div data-role = 'collapsible' id = 'set" + nextId + "'>
                  <h3>Heading " + nextId + "</h3>
                  <p>Hi!! This is collapsible content.</p></div>";
               $( "#set" ).append( content ).collapsibleset( "refresh" );
            });
            
            $( "#expand_last" ).click(function() {
               $("#set").children(":last").collapsible( "expand" );
            });
            
            $( "#collapse_last" ).click(function() {
               $( "#set" ).children( ":last" ).collapsible( "collapse" );
