How can I prevent users from adding a detailed description of the company by adding an article in K2. Leave only the opportunity to fill in additional fields. K2 is used as a catalog business. Thanks for help.

This may get you started

But tab "Content" is still active. I don't need "Content" tab. Necessary to allow users to enter only the additional fields

the link was to get started...you will probably find the tabs in the javascript that is in or connected to that file

Thanks, keep trying :-)
