Bootstrap accordion allow multiple to open
I have taken this accordion code from Bootstraps own source. But it doesn't collapse the others when I open a new one. Probably the question is already answered here, but I was unable to find it. Thanks for your help.

Answer
Like Jorn said, you are using the wrong classes. Here is your example with the minimum changes... Change
class="accordion-group"
to
class="panel panel-default"

And here is a more recent bootstrap accordion: http://getbootstrap.com/javascript/#collapse-example-accordion
