Horizontal orientation of the Global Navigation in SharePoint 2013

Hi,

I want to display the Global Navigation in SP2013 as below-

Home Site1   Site2

          SubSite1          SubSite2

          ThridLevelSite1

          ThirdLevelSite2

Site1 and Site2 are subsites under root site. SubSite1 and SubSite2 are subsites under Site1 and, ThirdLevelSite1 and ThirdLevelSite2 are subsites under SubSite1. If an user mouse hover on Site1, SubSite1 and SubSute2 should be displayed horizontally and, if an user mouse hover on SubSite1, ThirdLevelSite1 and ThirdLevelSite2 should be displayed vertically.

Please let me know if i can achieve the above functionality without using custom code.

Thanks in advance!!
