# Panel Element ## Content Tiles can display one or more panels. A panel can have nested panels. Panel elements of the type [PanelElement](/componentone/docs/win/online-tilecontrol/) class may contain child elements including nested panels. The child elements can be added at design time through the **PanelElement.Children Collection** editor or programmatically through the [Children](/componentone/docs/win/online-tilecontrol/) property. The following image displays a Tile with two docked panels with nested panels.
