Sub-navigation to another level?

[antknight]

This should be an easy one! Currently in the default theme for sub-navigation is the following code:

if($page->path != '/' && $page->rootParent->numChildren > 0) { 

echo "<ul id='subnav' class='nav'>";

foreach($page->rootParent->children as $child) {
$class = $page === $child ? " class='on'" : '';
echo "<li><a$class href='{$child->url}'>{$child->title}</a></li>";	
}

echo "</ul>";
}

Which works great for a structure like:

Home

 -Cricket Club

  --News

  --About

  --Contact

Class of 'on' is added to each of the news, about and contact pages when you are viewing them, but I want to go one more level. For example when viewing a child page of news, News link should still have class of 'on' applied.

Even after studying this post I couldn't figure it out!

How can I achieve this?

With a little addition:

$class = ($page === $child || $page->parents->has($child)) ? " class='on'" : '';

$page->parents returns a WireArray with all the parents and ->has checks if the current Nav-Item is in there.

This is very clever, I would never have been able to figure it out.

Many Thanks Wanze!
