How to have the title of a box at top and bottom

Question

box "title"

particpant xx

end box

Answer 1

Hello A.,

Currently this is not possible (only on the top, not on the bottom).
You can request a wanted feature for that if you want.

Then a workaround is perhaps to use notes as:

@startuml
box title
rnote over Bob, Alice : **same_title**
participant Bob
participant Alice
end box

participant Other

Bob -> Alice : hello
Alice -> Other : hello
...
...
...
...
...
...
...
Bob -> Alice : hello
Alice -> Other : hello

rnote over Bob, Alice : **same_title**

If that can help,
