The user can switch the views by using a link on the catagory page.
example (full view – title view)
This is about the category archives
i’m now working on a custom PHP solution wich is going to work fine, but my customer want plugins instead of custom functions.
<?php
$getArchiveView = $_GET["ArchiveView"];
$getCurrentCat = $_GET["cat"];
?>
<?php if ($getArchiveView == '1') { ?>
<a href="?cat=<?php echo $getCurrentCat; ?>&ArchiveView=2">Swich to headers</a>
<?php } else { ?>
<a href="?cat=<?php echo $getCurrentCat; ?>&ArchiveView=1">Swich to full</a>
<?php } ?>
