Left to right direction on composite state only?

Question

I'm using plantUml to draw some state diagram that have some composite state.

I would like to have the main layout as top to bottom, but in the composite state left to right direction.

Is that possible?

Answer 1

Try: State1 -> State2

(note one dash rather than two)

Also, section 7.5 of the document allows for other directions. This should also work:

State1 -right-> State2
