Delete menu item "Show / hide tab"

Question

The latest version of macOS Sierra adds a Show / Hide Tab menu item to the View menu.

He does it dynamically.

My application already has its own tab bar using the MMTabBarView library . I would prefer to continue using this library as it gives me backward compatibility with tabs as well as the ability to make some settings for tabs.

I see nothing in apples of NSDocument or NSDocumentController when deleting this menu item.

Does anyone have any suggestions as to how I can remove it?

NOTE. I do not want to just turn it off, I want to completely remove it. (Or, I think, it was not added in the first place).

In the Builder interface, open the attributes of your NSWindow, and you will see the "Tab mode" option. Set it to the Forbidden position.
