jQuery optgroups show/hide
<p>I'm using this jquery plugin 
<a href="http://www.erichynds.com/jquery/jquery-ui-multiselect-widget/" rel="nofollow">http://www.erichynds.com/jquery/jquery-ui-multiselect-widget/</a>
I have several optgroups for this application, some of which have options of more than 50 to go with an optgroup. Is there a way to be able to hide an optgroup when the user clicks on the heading?</p>

<p>Thanks.</p>
