Sharepoint Workflow "Else" missing

Hello,

I am trying to build a workflow using If Else function. Unfortunately I can't find an Else function anywhere. How do I add it?

Also, can you enter any additional conditions inside the transition stage? When I click just above the Go to: all the buttons in ribbon are greyed out.

This is a screenshot from this web and this is exactly what i am trying to achieve... Is that possible?

Thanks in advance!
