I would like to output custom options in the tab pane (description and attributes) on the detailview page of a product. I installed the easytabs Extension to use the catalogproductcms.phtml template files to be able to output a particular custom option. Inside the template file I put getLayout()->getBlock('product.info.options')->toHtml(); ?>. With this all the custom options are displayed in the browser. How do I have to modify this call to get only a single option that I can define by some attribute?
