Orientation#

Each dock can be laid out horizontally or vertically, independent of other docks.

Switching orientation#

For a floating dock, right-click it and choose Position Mode → Floating → Horizontal or Vertical
Management window → Properties → Position → Orientation

Fixed docks choose their orientation from the pinned edge. Top and bottom edges are horizontal. Left and right edges are vertical.

Icons are arranged left to right. This is the default for new docks and works well along the top or bottom of a screen.

Icons are arranged top to bottom. Works well pinned to the left or right edge of a screen, or as a sidebar-style launcher.

All features — collapse, auto-hide, widgets, effects — adapt automatically to the dock's orientation.
