BottomNavigationPositionMode

Specifies the position and behavior of the BottomNavigation when the page is scrolled (see example).

The possible values are:

• fixed(Default) — The BottomNavigation always stays at the bottom of the viewport, regardless of the page scroll position.
• sticky — Positions the BottomNavigation based on the user's scroll position. A sticky element toggles between

static and fixed CSS position property, depending on the scroll position. It is positioned static until a given offset position is met in the viewport - then it "sticks" in place like fixed positionMode.

type BottomNavigationPositionMode = "sticky" | "fixed";
