Make 16 colums /1 Panel restore on AET

Hi CRM Gurus,

I want to restore Make 16 colums /1 Panel on AET web UI configuration. I could not see on AET " Make 16 colums /1 Panel" that is unvisible. How can I restore the settings of Make 16 colums /1 Panel on AET web UI configuration ?

Kind Regards,

Fahrettin
