html - bootstrap initially collapsed element

Question

I am using the bootstrap template and I would like to change the way the accordion works by default.

How can I get the toggle to be closed when page is first seen (upon load)?

<div class="accordion-heading">
    <a class="accordion-toggle"
       data-toggle="collapse"
       data-parent="#accordion2"
       href="#collapseOne">Open!</a>
</div>
<div id="collapseOne" class="accordion-body collapse in">
    <div class="span6">
        <div class="well well-small">
            <div class="accordion-toggle">
                ...some text...
            </div>
        </div>
    </div>
    <div class="span2"></div>                            
</div>

Answer 1

When you expand or collapse accordion it just adds/removes a class "in" and sets the height:auto or 0 to the accordion div.

Demo

So in your accordion when you define it just remove "in" class from the div as below. Whenever you expand an accorion it just adds the "in" class to make it visible.

If you render the page with "in" bootstrap looks for the class and it will make the div's height:auto, if it not present it will be at zero height.

<div id="collapseOne" class="accordion-body collapse">
