Perch Pages Navigation from other pages

Excellent, spot on cheers.

While in the same navigation mode I'm creating a more standard navgroup.

I have category pages... and then product pages and I'm having a little trouble.

The main category page needs to show the sub-category's in the nav, which I have accomplished using the following code. This is fine and works well, just showing the sub-pages of the main section parent.

<?php perch_pages_navigation(
    array(
        'navgroup' => 'mechanics-of-fluids',
        'template' => 'right-menu.html',
        'levels'=>'2',
        'from-path'=>'/products/mechanics-of-fluids',
        'from-level'=>'2',
    )); ?>

for the sub-category pages and the product pages in that category, I want to show just the products in these categories, which I had hoped I could show like so;

<?php perch_pages_navigation(
    array(
        'navgroup' => 'mechanics-of-fluids',
        'template' => 'right-menu.html',
        'levels'=>'3',
        'from-path'=>'/products/mechanics-of-fluids',
        'from-level'=>'3',
    )); ?>

This outputs the product... but also it's parent and also the other sub page

Is this possible... or am I being over hopeful, I'd hoped not to have to set a master nav group for a section and then a second nav group per subsection

Yeah, that excludes the sub page (the product) and leaves me with the same result as the first snippit

What I want is to exclude the sub pages and just leave me with the product - which I thought should be at level 3.

'include-parent'=>false doesn't seem to have any effect either false or true

Ideally I just wanted to show the products which are sub pages of their parent

yeah, that doesn't do anything either

Totally appreciate how difficult this is for you to guess at... I'll see if I can break it down.

In the page structure I have

• mechanics-of-fluids (section leader page) - this is inside a top level folder called 'products'
• Fundamental Hydraulic Studies (sub category and sub page of the above)
• productpage.php (product page and sub page of above page

Basically three levels of pages

Ideally, I want to isolate and show only the products of the sub category on both the sub category page and the product page but I'm seeing the product, the sub category page and another sub category page on the same menu.

yeah, it seems to

To be honest, I'm not sure... this is how they appear in Perch

Yep, those are all covered by the same navgroup

i.e when I'm on the Fundamental Hydraulic Studies page, I just want to see it's sub pages listed in the menu and no others and when I'm on the Hydraulic Applied Studies page, I just want to see the sub pages from that.

Is that possible? or am I trying to attain something which can't be done at the moment?

Right no... this is the navgroup... thought it would nest them automatically. What have I done wrong?

Ok, I think this is where the problem is... I'm not totally sure how to do that.

Do I have to specify a second template in my navgroup php? like this

perch_pages_navigation(array(
    'template' => array('item.html', 'subitem.html')
));

or should this be something set in the admin.

I've done an fairly extensive search in the perch docs and couldn't find much that specifically related to nested navigation,

Really appreciate your help, I know it must be frustrating. This is the deepest I've ever had to go with nav groups and I'm a little out of my comfort zone (in a good way though)
