+Items within a ListView also allow for additional content used to add context or provide additional actions to items. Descriptions, illustrations, and thumbnails can be added to
 the children of `<Item>` as shown in the example below. If a description is added, the prop `slot="description"` must be used to distinguish the different `<Text>` elements.
 Additionally, components such as `<ActionButton>`, `<ActionGroup>`, and `<ActionMenu>` will be styled appropriately if included within an item. Providing the `hasChildItems` prop
 to an `<Item>` will add a chevron icon to the end of the row to visually indicate that the row has children.
