How is a plantuml diagram with nested boxes oriented vertically?

Question

I am trying to made a diagram that grow vertically (with the trick of hidden arrows to down), but plantuml is still drawing horizontally.

This is a tiny example of diagram

@startuml
skinparam linetype ortho
top to bottom direction

rectangle aaa {
  rectangle aaa111
}

rectangle bbb {
  rectangle ccc {
    rectangle ccc111
    rectangle ccc222
    rectangle ccc333
    
    aaa111 -right-> ccc111

    ccc111 -[hidden]-> ccc222
    ccc222 -[hidden]-> ccc333
  }
  rectangle ddd {
    rectangle ddd111
    rectangle ddd222

    ddd111 -[hidden]-> ddd222
  }
  rectangle eee {
    rectangle eee111
    rectangle eee222

    eee111 -[hidden]-> eee222
  }

  ccc -[hidden]-> ddd
  ddd -[hidden]-> eee
}

And this must be like:

aaa -> ccc
  
       ddd

       eee

Answer 1

It's not logical, but left to right direction will do it:

@startuml
skinparam linetype ortho
'top to bottom direction
left to right direction

rectangle aaa {
  rectangle aaa111
}

rectangle bbb {
  rectangle ccc {
    rectangle ccc111
    rectangle ccc222
    rectangle ccc333
    
    aaa111 --> ccc111

    ccc111 -[hidden]left-> ccc222
    ccc222 -[hidden]left-> ccc333
  }
  rectangle ddd {
    rectangle ddd111
    rectangle ddd222

    ddd111 -[hidden]left-> ddd222
  }
  rectangle eee {
    rectangle eee111
    rectangle eee222

    eee111 -[hidden]left-> eee222
  }

'  ccc -[hidden]-> ddd
'  ddd -[hidden]-> eee
}
