I saw you are using an iframe to load your links inside, so you could use, for example, something like this:
// simulate a click on the menu toggle button on menu item select in mobile view
$('#main-menu').bind('select.smapi', function(e, item) {
var obj = $(this).data('smartmenus');
if (obj.isCollapsible()) {
$('#main-menu-state')[0].click();
}
});
