Reply To: Different sets of elements for creating menus with and without demo data

Please find here how to create and manage menu https://codex.wordpress.org/WordPress_Menu_User_Guide

I understand how to drag menu items to the menu area.
But I do not understand why in the absence of demo data, these items are not in the menu designer.

With the demo data, the item “Products” exists (attachment 1)
Without the demo data, the item “Products” does not exist (attachment 2)

Why?
