I'm creating a list using collapse in an interaction of loop , but they're all starting open, I'd like only the first item of my collapse to be open.

If you double click on one of the items, it closes all the others, leaving only what was clicked.

My view

<div class="panel-group" id="accordion" role="tablist" aria-multiselectable="true">
    @for (int i = 0; i < 10; i++)
    {
        <div class="panel panel-default">
            <div class="panel-heading" role="tab" id="heading_@i">
                <h4 class="panel-title">
                    <a data-toggle="collapse" data-parent="#accordion" href="#collapse_@i" aria-expanded="true" aria-controls="collapse_@i"
                       @{ if (i == 0) { <text> collapse</text>} else { <text></text>}}>
                        Collapsible Group Item #@i
                    </a>
                </h4>
            </div>
            <div id="collapse_@i" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="heading_@i">
                <div class="panel-body">

    }
</div>

I'm not sure where you set the element to collapse, but put a (i == 0) ? 'collapse' : ''; . It should not be the best solution, but it solves your problem.

The solution is to change the div:

<div id="collapse_@i" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="heading_@i">

for

<div id="collapse_@i" class="panel-collapse collapse" role="tabpanel" aria-labelledby="heading_@i">

remove the style in

The style in causes the element where it is used to be visible, as can be seen in its definition that is found inside the file bootstrap.css

.collapse.in {
  display: block;
  visibility: visible;
}
