Creates a Panel shown on demand that renders in fixed location.
- Implementing a PanelOverlay
Using the PanelOverlay container type in a component.
Used in a UX component with other Panels. The controls inside a PanelOverlay contaienr are rendered in a fixed position relative to an edge of the Panel containing the PanelOverlay. The PanelOverlay is typically used to display 'floating' content (such as a toolbar) over a Panel. If the PanelOverlay container is inside a PanelNavigator, the floating content is displayed for every Panel in the PanelNavigator. If the PanelOverlay is inside a PanelCard, the floating content is only visible when the PanelCard containing the PanelOverlay is visible.
