By default, the boot lock bar is closed

You just need to change this:
<div class="panel-body">
For this:
<div class="panel-body" style="display:none;">
And change slideUp () to slideDown (), and same for slideDown () with slideUp ().
Also change this:
<span class="pull-right clickable collapse in"><i class="glyphicon glyphicon-plus"></i></span>
For this:
<span class="pull-right clickable collapse in"><i class="glyphicon glyphicon-minus"></i></span>
Everything should work as you mentioned in your question now.

You can use the Bootstrap collapse component which already has most of the required logic:
<div class="panel-heading">
<h3 class="panel-title">Panel 1</h3>
<button class="btn btn-primary pull-right" type="button"
data-toggle="collapse" data-target="#collapseExample">
<i class="glyphicon glyphicon-plus"></i>
</button>
</div>
<div class="collapse" id="collapseExample">
<div class="panel-body">Panel content</div>
</div>
Also, only a little JavaScript is needed to change the button icon:
$(document).on('click', '.panel-heading button', function(e) {
var $this = $(this);
var icon = $this.find('i');
if (icon.hasClass('glyphicon-plus')) {
$this.find('i').removeClass('glyphicon-plus').addClass('glyphicon-minus');
} else {
$this.find('i').removeClass('glyphicon-minus').addClass('glyphicon-plus');
}
});

I am using the reference code for you, just follow the code, no need for any click function, bootstrap 'data-toggle = "collapse"' handles it automatically.
CODE:
<div class="panel-group" id="steps">
<!-- Step 1 -->
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#steps" href="#stepOne"><SPAN TAG></a>
</h4>
</div>
<div id="stepOne" class="panel-collapse collapse">
<div class="panel-body">
<div class="form-group">
<label class="col-lg-2 control-label">Sub-Category Name</label>
</div>
</div>
</div>
</div>
</div>
Just put a span tag instead and use the pull-right class, the bootstrap icon you need http://getbootstrap.com/components/
I hope this works.
