Добавить open caret on bootstrap accordion

Question

Я пытаюсь добавить открытую каретку на аккордеон с использованием глифной бутстрапа, теперь я могу легко управлять, если есть только ссылка, но изменение в том, что я хочу, чтобы полный заголовок был доступен для кликабельности, вот мой код теперь

<div class="panel-group" id="accordion"> 
    <div class="panel panel-default"> 
    <div class="panel-heading" data-toggle="collapse" data-parent="#accordion" data-target="#collapseOne">

      Collapsible Group Item #1 
     </a>

    </div> 
    <div id="collapseOne" class="panel-collapse collapse in">

Answer 1

Добавьте это в CSS:

.panel-heading { 
     cursor: pointer; 
     position: relative; 
    } 

a { 
    text-decoration: none !important; 
} 

span.indicator { 
    position: absolute; 
    right: 5px; 
    top: 15px; 
} 

И <span class="glyphicon glyphicon-triangle-bottom indicator"></span> внутри <div class="panel-heading">

$(function(){ 
    $(".panel-heading") 
     .on("click",function(){ 
      $(".indicator").toggleClass("glyphicon-triangle-bottom glyphicon-triangle-left"); 
     }); 
}); 

При нажатии на .panel-heading переключает стрелку снизу слева.
