HtmlDropDownMenu with click able parent label

[mmulligan03]

I've created a class to build a drop down menu from a database.  The creation of the menu works as planned but what I can't figure out is how to make the parent item a link to a page. 

For instance I might have a menu structured like so:

1. My Account
   1. Billing
      1. Pay Bill
      2. Change Billing
   2. Profile

etc...

The way my current code works is I cannot click on Billing and have it bring me to the main Billing page

I know that when writing this out using tags I can specify a <f:facet like so:

<rich:dropDownMenu>
            <facet name="label" >
                <s:link view="/billing.xhtml" value="Billing" />
            </facet> 
...

and that will give me a click able link.  How can I do this in my code below? (the _parseSubMenu method is where the HtmlDropDownMenu is created)
