Header.vm, customize menu, ask for security-constraints ??

[Javier padrón]

In decoration/layout/layoutName/header.vm', have next code to generate standar 
menu, in this case iterate over all standar pages and filter by 'isHidden' to 
show only public pages

// ----- header.vm ----
<ul>Pages Menu
#foreach($element in $pagesStandardMenu.elements.iterator())
            #if ($element.isHidden()== false)
                    #set($tabTitle = $element.getTitle($preferedLocale))
                    #set($tabName = $element.getShortTitle($preferedLocale))
                      #if($element.isSelected($site))
                        <li title="$!tabTitle"><b>${tabName}</b></li>
                      #else
                        #set($tabUrl = $jetspeed.getAbsoluteUrl($element.url))
                                    <li title="$!tabTitle"><a 
href="$tabUrl">${tabName}</a></li>
                      #end
                #end
            #end
#end
</ul>


Good, now I'have others pages with

    <security-constraints>
        <security-constraints-ref>private-view</security-constraints-ref>
    </security-constraints>

...these pages do not have to appear in the menu when the user has not 
initiated session, and yes when the user has validated itself, this works very 
well, they are taught and they hidden when they must.

The problem is that I want to show of special form the privated pages, now is 
thus:

// --- User NO loged ---
<ul>Pages Menu
            <li>public page 1</li>
            <li>public page 2</li>
            <li>public page 3</li>
            ...
</ul>

// --- User Loged OK ---
<ul>Pages Menu
            <li>public page 1</li>
            <li>public page 2</li>
            <li>public page 3</li>
            ...
            <li>private page 1</li>
            <li>private page 2</li>
            ...
</ul>

// -- Finally, I want that one is thus! ---
<ul>Public Pages Menu
            <li>public page 1</li>
            <li>public page 2</li>
            <li>public page 3</li>
            ...
</ul>
<ul>Private Pages Menu
            <li>private page 1</li>
            <li>private page 2</li>
            ...
</ul>

Then, my question is how I can do this in the file header.vm? While iterate the 
pages I can ask '#if ($element.< whichMethodName>)' in order to know if a page 
private or no? How?

Thanks!
