Add or Edit Menu Items Permission
Add or Edit Menu Item is a portal permission that allows managers to add new menu items or edit the menu items they have created.
When this permission is turned on, the + Add Menu Item button will appear in the Menu Items tab in the portal. The Edit button (pencil icon) will appear next to the menu items the manager has added, but not those added by other managers or portal administrators.
User type permissions can be changed by Portal Administrators under the Users tab in the portal. See How to Update Permissions.
