JavaScript

$(function() {
  $('a.accordion-toggle').click(function(e) {
    e.preventDefault();
    if (!$(this).parent().hasClass('accordionPannelActive')) {
      $('.accordion-heading').removeClass('accordionPannelActive').find('a').removeClass('accordionPannelActive');
      $(this).parent().addClass('accordionPannelActive').find('a').addClass('accordionPannelActive');
    } else {
      $('.accordion-heading').removeClass('accordionPannelActive').next().removeClass('accordionPannelActive');
      $(this).parent().find('a').removeClass('accordionPannelActive');
    }
  });
});

CSS

.accordionPannelActive {
      background-color: #8dc640!important;
      color: white !important;
}

a.accordion-title:focus {
      color: inherit;
      text-decoration: none;
}

.panel-default > .panel-heading {
      background-image: none;
}

a.accordion-title:hover {
      color: inherit;
      background-color: inherit;
      text-decoration: none;
}

.panel-default > .panel-heading {
      background-image: none;
}
.panel-title{
      display:block;
}

Needs: jquery.min.js, jquery.min.js, bootstrap.min.css, bootstrap-theme.min.css and bootstrap.min.js

Answer 2

I was also Looking to add an "active" class or similar but I noticed during inspection that when inactive all the links have a class of "collapsed" that is removed when the tab/link is selected, thus I simply tageted the tab without the "collapsed" class.

Answer 3

You can use the Collapse events for this.

$(function() {

    $('.accordion').on('show', function (e) {
         $(e.target).prev('.accordion-heading').find('.accordion-toggle').addClass('active');
    });

    $('.accordion').on('hide', function (e) {
        $(this).find('.accordion-toggle').not($(e.target)).removeClass('active');
    });

});​

Answer 4

I've tried Michael D. Irizarry's solution but that didn't work for me. So I came up with my own code:

$(function() {
    $('a.accordion-toggle').click(function(e) {
        e.preventDefault();
        if(!$(this).parent().hasClass('active')) {
            $('.accordion-heading').removeClass('active');
            $('.accordion-body').removeClass('active');
            $(this).parent().addClass('active').next().addClass('active');
        } else {
            $('.accordion-heading').removeClass('active');
            $('.accordion-body').removeClass('active');
        }
    });
});

If the accordion-heading already does not have a class of active, all accordion-headings & bodies lose the active class, and the one that has been clicked and it's corresponding body tag will get the class added.

If it already has the class active (so if it is already open and been clicked) then the active class is removed and nothing else happens.

Answer 5

I think this is the simplest way so far.

$('a.accordion-toggle').on('click', function () {
  $('a.accordion-toggle').removeClass('active');
  $(this).addClass('active');
});
