Disable participans and actors at the bottom of sequence diagrams?

Question

Standard sequence charts as drawn in books or with commercial applications (EA) usually don't render objects (participants, Actors etc) at the bottom of the diagram.

Is it possible to disable this feature in PlanUML as well?

Answer 1

You can use the hide footbox command.
For example :

@startuml
hide footbox
title Footer removed
Alice -> Bob: Authentication Request
