Accordion Collapsible

Accordion Collapsible


I've searched and can't figure it out...
This is my code and its all working except for the collapsible
switch. The accordion loads with all headers closed, but I can't
collapse a header once its open.
$(document).ready(function(){
$('#content').accordion({
            active: false,
            collapsible: true,
            autoHeight: false,
            header: 'h3'
    });
    });
