how to add a newly created participant in a exist box

Question

Hi, guys,

I got a problem to add a newly created participant in a exist box, instance as below:

I want newly crreated Bob1 also in box B1, and B1 showed as a single box, does anybody have the experience to do that?

Many thanks.

Hi,

you could make it like this (only list it in the box and then you can still create it afterwards)

@startuml
box B1
participant Alice order 10
participant Bob order 20
' add it here <----------------
participant Bob1 order 19
end box

box B2
participant Coco order 30
participant David order 40
end box

Alice -> Bob: hello
Bob -> Coco: hello
Coco -> David : hello
return hi

Coco -->Bob:hi

' you can create it here <----------------
create Bob1
Bob->Bob1:new
