The "group" keyword in the sequence diagram currently group messages from all participant in between the group definition and the "end group" statement.

My question is: is there a way that I can only create a group, which group messages from one or more participants? Like what note does..

for example:


participant A

participant B

participant C

group over A, B : This ideally only group messages from/to A and B

A ->> B : Message 1

B ->> C : Message 2

C ->> A : Message 3

A ->> C : Message 4

end group


Thanks a lot guys.

Sorry, I am not sure to understand the need.

Could you use an image editor to edit the following image and to show us what you are expecting :

Sorry I couldn't manage to find a way to upload a image in my post. But what I need is simply to:

Resize the group box in your reply, make it only cover the lifeline of "A and B". In another words, the group box should only cover
> Message 1
> Left half of Message 3
> Left half of Message 4

I hope I explained it better this time.

Thanks :)
