You can change the Cairo-dock configuration to match your need. I like the default display but may be you don’t. Configuration menu can be accessed by doing right click on the Cairo dock then select ‘Configure’ menu.
PART 1. SYSTEM
Configuration 1: Position on Screen
The default is bottom. You may change to Right, Left or Top. I’ve tried to change it to right, but it’s didn’t work. It moved to right but I can’t access it. May be, it’s be caused my screen resolution.
Configuration 2: Auto Hide
I suggest to activate the auto hide function. Otherwise when you open an application, Cairo dock will stay on the top. You can see the sample below.
