AppBarPositionMode

Represents the available position modes of the AppBar (see example).

The possible values are:

• static—Positions the AppBar according to the normal flow of the page.
• sticky—Positions the AppBar based on the user's scroll position. A sticky element toggles between the static and fixed CSS position property, depending on the scroll position.
• fixed—Positions the AppBar relative to the viewport. The component always stays in the same place even if the page is scrolled.
