Menu details in document properties
Every resource that can be shown in a menu must have the Shown in Menu option enabled in the resource's setting page. The Resource setting page also has two other options related to menus:
Menu title—what to show in the menu. The resource title is used, if this value is left blank.
Menu index—when a list of the resources that are to be listed in the menu is created, the menu index can be used to sort the resources in the required order. Menu index is a number, and when creating lists we can specify how we want to use the index.
