Mermaid: SequenceDiagram: 3+ Alternative Paths

[michaeltlombardi]

Overview

Is it possible to have multiple alternate paths in a sequence diagram?

e.g. If A then X, else if B then Y, else if C then Z.

If not (and my tests to do so failed), is this functionality that it makes sense to add?
Example below.

Example

sequenceDiagram
Participant alpha
Participant bravo
alpha->>bravo: request resource
alt has resource
    bravo->>alpha: return resource
else does not have resource
    bravo->>charlie: request resource
else resource blacklisted
    bravo->>alpha: return error message
end

Edit: Initially posted the wrong example.

Sorry that is currently not possible

You can do single else statements though as in the example:

And... Yes it would make sense to add it. I would welcome a pull request with this. 👍

I've got the javascript skills of a toddler, but I will look into this in the future, time permitting.
