Automatically set parent menu item
When creating a menu page it can be very helpful to automatically set the parent item subject to the content type. For example, all new case studies should always reside under the parent menu item "Case Studies".
To achieve this use the Auto Menu module.
Once the module has been enabled it is configured under the "workflow" options that reside under each content type.
Restrict Parent Menu Options
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.
