Modifying Bootstrap Accordion

Question

I have added a bootstrap accordion in my project.

I realise the only showing section can be closed too, but I hope that at least one section stays open in any situation. I'm not sure how I can prevent the only showing section from closing?

How do you make Twitter Bootstrap Accordion keep one group open?

$('.panel-heading a').on('click',function(e){
if($(this).parents('.panel').children('.panel-collapse').hasClass('in')){
    e.stopPropagation();
}
// You can also add preventDefault to remove the anchor behavior that makes
// the page jump
// e.preventDefault();
});

It will prevent the only showing window from closing.
