 social bookmarking websites in a two-column drop down menu is really a great features as it appears only when someone hovers the mouse over the Bookmark button - the icons and links stay hidden or invisible otherwise.If you are interested in putting social bookmarking icon in dropdown Menu then you can easily do that,as you have alredy seen my previous post   on how to add socialbokmarking buttoms in blog post , so it is more easy for you , the only thing you have to do is to add below javacode anywhere you want to add this Social Bookmarking Icons.

<!-- AddThis Bookmark Button BEGIN -->
<script type="text/javascript">
  addthis_url    = location.href;  
  addthis_title  = document.title; 
</script><script type="text/javascript" src="http://s7.addthis.com/js/addthis_widget.php?v=12" mce_src="http://s7.addthis.com/js/addthis_widget.php?v=12" ></script>
