foldable section

Hi All,

I am looking to have a section by default collapsed/folded when the page loads. This task was very straight forward in 9.8 (Totals>Add>Add section>Expand initially) but in 10 I cannot find this checkbox anymore.

I also followed the "how to work with foldable section " under the help page but no luck.

I am using following code in Javascript OnLoad event, but it does not work.
var section="section3";

$("#section"+section).hide();

$("#section"+section+"Butt").attr("src", settings.global["webRootPath"] + 'images/plus.gif');
This is the code behind the editor page (html):
<DIV class="panel panel-default form-section">

<DIV class="panel-heading" role="tab" {$section_section3_headattrs} data-toggle="collapse" href="#section3" aria-expanded="true" aria-controls="section3">

<H4 class="panel-title">

<a role="button" >

Standard Cost in US and CAD

</a>

</h4>

</div>

<DIV class="panel-collapse collapse in {$section_section3_xtrclass}" role="tabpanel" {$section_section3_attrs} id="section3">

<DIV class="panel-body">
Any suggestions please ?

Thx
