Bootstrap accordion menu not working

Question

I have designed a accordion menu like in the image. If you click a menu the opened menu will get closed.This is the functionality of accordion. But in this design i've clicks menu one by one but the previous one was not closing.. How to fix this issue? Thanks in advance

jQuery(document).ready(function () {
    var acc = document.getElementsByClassName("accordion");
    var i;
    for (i = 0; i < acc.length; i++) {
        acc[i].onclick = function () {
            this.classList.toggle("active");
            this.nextElementSibling.classList.toggle("show");
        };
    }
    
});

Answer 1

Please have a look at this jQuery approach:

if (!$(this).hasClass("active")) {
     var oldAcc = $(".accordion.active");
     oldAcc.toggleClass("active");
     oldAcc.next().toggleClass("show");
}

With above code we are getting reference to already opened accordion and closing it before opening the other one.

jQuery(document).ready(function() {

  $(".accordion").click(function() {
    if (!$(this).hasClass("active")) {
      var oldAcc = $(".accordion.active");
      oldAcc.toggleClass("active");
      oldAcc.next().toggleClass("show");
    }
    $(this).toggleClass("active");
    $(this).next().toggleClass("show");


  });

});

Answer 2

Note: first this is not bootstrap accordion

here is solution just add these 2 lines when you click

$(".accordion").removeClass("active");
$(".panel").removeClass("show");

better to write some thing like this way (Pure JQuery)

jQuery(document).ready(function() {
    $(".accordion").click(function(){
    $(".accordion").removeClass("active");
    $(".panel").removeClass("show");
    $(this).addClass("active");
    $(this).next(".panel").addClass("show");
  })
});

fiddle

Answer 3

If you're simply wanting one to slide down while the others slide back up, use the following code:

$('.accordion').click(function() {
    var targetElement = $(this).next('.panel');
    targetElement.slideToggle();
    targetElement.siblings('.panel').slideUp();
});

ENJOY... :)

Answer 4

Just do it right with jQuery:

jQuery(document).ready(function () {
  $('.accordion').on('click', function() {
    var target = $(this),
      activeEl = $('.active'),
      openedEl = $('.show');

      // remove the active state
      activeEl.removeClass('active');
      openedEl.removeClass('show');
      // add active state for unactive elements only
      if(!target.is(activeEl)) {
        target.addClass('active');
        target.next().addClass('show');
      }
  });
});
