a button to close all opened accordion Bootstrap

Question

I want to ask how to make a button to closing all opened accordion (Still toggle). The button function just to close when one of the accordion is opened. Maybe it's something weird, where the accordion has a toggle already. but in my case I need an external button to closing an opened accordion item.

I hope I can find the answer here, Thank You!

Answer 3

Toggle the according will do below things:

Using class .collapse to hide content

Using .collapse.show to show content

What you need to do is to remove the show class for the expanded accordings when user clicked the close button.

$(document).ready(function() {
  $(".close-button").on('click', function() {
    $('#accordionExample').find('.card .collapse.show').removeClass('show'); /* this closes the opened accorion */
  });
});
