Hide product fields

Hi,

I have read almost every post on the topic, but I still cannot manage to solve my problem. I would like to hide some fields for the products as shown on the printscreen attached. I cannot understand where can I change this:

www.hikashop.com/forum/content-creation/...-backend.html#163930

"No there is no option to do that, so if you don't want them to be displayed, you'll just have to use some CSS property like :
display : none;
Or directly edit the code of files of your back-end template through "Hikashop->Display->Views"."

I want the vendors to change the details for their products, but they will be confused with so much information= I want to display for the vendors only certain fields.

Thanks in advance for your help
