Hi Juergen
To remove the sticky header feature you can simply remove the following from your templates scripts.php (../templates/[YourTemplate]/php/scripts.php)..
<!-- Sticky Div -->
<script type="text/javascript" src="/<?php echo $this->baseurl ?>/templates/<?php echo $this->template ?>/js/jquery.sticky.js" charset="utf-8"></script>
<script type="text/javascript" >
jQuery(window).load(function(){
jQuery("#container_hornav").sticky({ topSpacing: 65 });
});
jQuery(window).load(function(){
jQuery("#container_header").sticky({ topSpacing: -20 });
});
</script>
The above is for the Enlighten template however our Habitat template would be similar.
