+| `overlayPositioning` | `overlay-positioning` | Determines the type of positioning to use for the overlaid content. Using `"absolute"` will work for most cases. The component will be positioned inside of overflowing parent containers and will affect the container's layout. `"fixed"` should be used to escape an overflowing parent container, or when the
