Dear sir , I have missing functionality of the SideNav.jspf in Portal v6.1 , which I used the code provided under this URL , , the SideNavigator is collapsed first rendering , & expands its selected page subs , when select .but have this illogical attitude :

If I press on a node & it was expanded , to view the child nodes , when I click on another sibling node , but which is individual – have no child nodes , it does not collapse the already expanded one .
