Items / Dot Strip Positions

The NavigationStripPosition specifies the placement position of the navigation bar items such as thumbnail or dots relative to the slider area.

There are four available positions,

  • Bottom - Sets the position of the navigation bar items to the bottom.
  • Left - Sets the position of the navigation bar items to the left.
  • Top - Sets the position of the navigation bar items to the top.
  • Right - Sets the position of the navigation bar items to the right.
