as comment suggests, it's not clear you're trying do, think got it. didn't make changes html or css. modified javascript little. 

$('.checkbox').on('click', function (e) {     var $this = $(this),         $links = $('.checkbox');      if ($this.hasclass('selected')) {         $this.removeclass('selected');     } else {         $this.addclass('selected');     }      $('.box').hide();     if ($(".checkbox:checked").length > 0) {         // 1 checked         $.each($links, function (k, v) {             $this = $(v);             if ($this.hasclass('selected')) {                 anyselectedcheckbox = true;                 var cat = $this.data('categorytype');                 var nam = $this.data('categoryname');                 $('.box:has(div[data-category-type="' + cat + '"],div[data-category-name="+nam+"] )').show();             }          });     } else {         // none checked         $('.box').show();     } });
