jQuery Accordion

jQuery Accordion

I am using Accordion to collapse a section in my form. I do not have multiple sections, just one and i want it to be in collapse condition at the start. Is it possible?

This is my code sample:

jQuery Call to Accordion function:

$('#optional').accordion({collapsible:true});

and my html

<div id="mandatory">Mandatory content here....</div>
<div id="optional">Optional content here....</div>

Thanks,
Sampat.
