Restrict Parent Menu Options

Question:
How to restrict parent menu options to relevant items when adding a new page

When a content author adds a node they are typically required to select a parent item.

However, the default display of parent menu options shows items that are irrelevant and confusing.

Therefore, it is more user friendly to show only the menu items of relevance. This can be achieved by only displaying a specific menu and its items through use of the module Menu Settings per Content Type.
