Accordion with Bootstrap 3

Question

I am trying to make accordion with Bootstrap Collapse . I have this HTML :

<ul id="ul">
    <li>
        <div class="first">
             <button>
                 <i class="fa fa-caret-down" aria-hidden="true"></i>
             </button>
             <a href="#">Name</a>
         </div>
        <ul class="collapse">
            <li>
                <a href="#">item 1</a>
            </li>
            <li>
                <a href="#">item 2</a>
            </li>
        </ul>
    </li>
</ul>

When I click on #ul > li , it must show ul.collapse .

I am using this JS :

$('#ul > li').on('click', function (e) {
    $('.collapse.in').collapse('hide');
    $(this).find('.collapse').collapse();
});

, but it works only first 2 clicks for open and close and after that, it doesn't work. I need to do this with JS .

Answer 1

Try that

 $('#ul > li').on('click', function (e) {
  if($('.collapse').hasClass('in')) {
    $('.collapse.in').collapse('hide');
  } else {
      $(this).find('.collapse').collapse('show');
  }
});

it can be written in better form but that will fix your issue.

Option 1: You can use slideToggle() from jQuery.

 $('#ul > li').on('click', function(e) { $(this).find('.collapse').slideToggle(); }); 

 .collapse { display: none; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <ul id="ul"> <li> <div class="first"> <button> <i class="fa fa-caret-down" aria-hidden="true"></i> </button> <a href="#">Ресторант Топ Мания</a> </div> <ul class="collapse"> <li> <a href="#">Обедно меню</a> </li> <li> <a href="#">Вечерно меню</a> </li> </ul> </li> </ul> 

Option 2: use collapse('hide') and collapse('show');

 $('#ul > li').on('click', function(e) { $('.collapse.in').collapse('hide'); $(this).find('.collapse').collapse('show'); });
