hot bar location

[mst272006]

is there away to turn the hotbars so that they are going up and down. I have been looking for a way to do it and i have not found any. I do miss that form playing wow for a year. it just takes up so much room when you have like 4 or 5 hot bars up. it would make it easier to have a couple on the side and the other on the bottom. if someone knows please let me know?
