How do I get my accordion to load with all the menus closed?

If you want to close all collapsed on page load:

In class collapse in replace it to class collapse.

id="collapseOne" class="panel-collapse collapse **in**" role="tabpanel" aria-labelledby="headingOne">

Update to:

id="collapseOne" class="panel-collapse collapse" role="tabpanel" aria-labelledby="headingOne">

From the doc:

If you'd like it to default open, add the additional class in.

In other words, leave out the "in" and it will default to close. http://jsfiddle.net/JBRh7/
