Accordion with arbitrary elements, e.g. <dt> and <dd>

[Niklas-Peter]

Is a use as below not intended or am I doing sth. wrong, I have already checked it many times? Obviously the class "in" is not removed from the other items when clicking on another one.

Here online: http://jsfiddle.net/h95sT/

    <dl id="faq">
    <dt data-parent="#faq" data-target="#answer-1" data-toggle="collapse">
    Term 1</dt>

    <dd class="collapse in" id="answer-1">description 1</dd>

    <dt data-parent="#faq" data-target="#answer-2" data-toggle="collapse">
    Term 2</dt>

    <dd class="collapse" id="answer-2">description 2</dd>
    </dl>
