Would it be possible to insert the
pageclass_sfx - support for joomla's menu item in virtuemart templates - permanently?
Like this:
$app = JFactory::getApplication('site');
$pageclass = & $app->getParams('com_content');
<div class"<?php echo $pageclass ->get('pageclass_sfx');">
...
</div>
as child of
<div class="component-content">
</div>
