hi aardcom,
You want to hide the header and top nav section for a determining article,right ?
example you want to hide the main navigation in a article page you can try as below
Open the file of templatesja_drimiaindex.php, Look for this
<div id=”ja-mainnav”>
<?php
//Gen menu for CSS, MOO
//Gen first level menu for Split, Dropline
$jamenu->genMenu (0);
?>
</div>
change it to
<?php if(JRequest::getCmd(‘option’)==’com_content’ && JRequest::getCmd(‘view’)==’article’ && JRequest::Int(‘id’)==your article id goes here) { ?>
<div id=”ja-mainnav”>
<?php
//Gen menu for CSS, MOO
//Gen first level menu for Split, Dropline
$jamenu->genMenu (0);
?>
</div>
<?php } ?>
The snap code I added here help to detect if it is on a article page with a determine id
Notice replace ‘your article id goes here’ with actual article ID.
