There are two type of products in the shop:
- products which are always on stock
- products which are only available on special order

I want the customer can distinguish them easily by adding a different background color to each type.

My plan was to make a second product type based on the general-type and then just change the template file.

I followed this thread. The new type is called product_nos.

I can see the new type in the admin area. I added some html in
includes/templates/myTemplate/templates/tpl_product_nos_info_display.php.

Then i add a new product of this type, but the changed background is never shown in the detailed view of the product.

Adding the changed background colour to the list view is the next thing and probably more complicated.

Thanks for any ideas.
