AppBarPositionMode

Specifies the positionMode of the AppBar (see example).

• The possible values are:
• static (Default)—Does not position the AppBar in any special way. It is positioned according to the normal flow of the page.
• sticky—Positions the AppBar based on the user's scroll position. A sticky element toggles between static and fixed CSS position property, depending on the scroll position.
• fixed—Positions the AppBar relative to the viewport. It always stays in the same place even if the page is scrolled.

type AppBarPositionMode = "static" | "sticky" | "fixed";
