Hide empty autonavs

Permalink
Hey! I have an extra autonav called Sub-Nav on EVERY page in my site, so if the page "gets children" the children automatically shows up in Sub-Nav.

Now, is there a way to hide the <ul id="subnav"></ul> if there is no <li> inside it? This is only because I want my site to validate as xhtml strict.

Thank you!

Now I'm producing like my fifteenth C5-based website and I still have this problem. Is there a way to hide these empty, ugly <ul>'s until someone fill them up?

I've been experimenting with if "($_c->getNumChildren() == 1)" but I don't get it to work as it should.

Thanks in advance,
Alejandro

Is this extra <ul> added by C5 or manually by you?

This is what worked for me:

<?php /* top of page */
$subnav = new Area('Sub Nav');
?>
<?php /* later on page*/ if( $subnav->getTotalBlocksInArea($c) > 0 || $c->isEditMode() ): ?>
<ul id="subnav"> <?php $subnav->display($c); ?> </ul>
<?php endif; ?>


$c->getNumChildren counts up all the blocks in the collection; use the getTotalBlocksInArea method on the Area instance instead.
