I have this accordion thing from bootstrap. The arrow icons point down.
This is a bug in bootstrap. If you inspect your markup when you toggle one of the headings that has a class of .accordion-toggle it toggles it from having the class collapsed or not. When you click a different heading to the one that is open though it doesn't add the class of collapsed onto the heading of the open element. This fixed it for me:
$('.accordion-toggle').click(function() {
if($(this).hasClass('collapsed')) {
$('.accordion-toggle').not(this).addClass('collapsed');
}
});
