id string null No 0.1.0

The ID of the content item. This property can be used to identify the item. The ID must be unique and only consist of letters, numbers, and the special characters "_", "-", ".".

type string "default" No 0.1.0

The type of the content item.

  • "default": Default item.

The icon and label properties are typically used with this type. Additionally, the extensionLabel and extensionIcon properties are available for this type.

Note: Please note that a content page must have at least one selectable item in order to be displayed (e.g. a content page that only contains items of type "space", cannot be displayed). This does not apply to a content page that is displayed as overlay/underlay page, because this page can only contain items of type "space".
