    :TEST 2;

Hello, sorry I cannot post any image due to corporate restrictions. When using connectors 1-2-3, the layout is good. If I change connectors to activity labels, the layout is overly complex. Is there a way to have the layout from the left, but with activity labels instead of connectors ? Can I add instructions in the code to achieve the same ?

Hello J., and all,

Here is a proposal using `elseif` and `!pragma useVerticalIf on`:

@startuml
!pragma useVerticalIf on
  if (condition 1) then(yes)
    :TEST 1 ;
    detach
  ( no ) elseif(condition 2) then (yes)
    :TEST 2;
    detach
  ( no ) elseif(condition 3) then(yes)
    :TEST 3;
    detach
  else(no)
  endif
stop
@enduml

Enjoy,
If that can help,
Regards,
Th.

Here are some other proposals:

@startuml
if (condition 1) then(no)
  if(condition 2) then(no)
    if(condition 3) then(no)
      label l;
    else(yes)
      :TEST 3 ;
      detach
    endif
  else(yes)
    :TEST 2;
    detach
  endif
else(yes)
  :TEST 1;
  detach
endif
stop
@enduml

Or:

@startuml
  if (condition 1) then(no)
     label l;
  else(yes)
    :TEST 1 ;
    detach
  endif
  if(condition 2) then(no)
     label l;
  else(yes)
    :TEST 2;
    detach
  endif
  if(condition 3) then(no)
     label l;
  else(yes)
    :TEST 3;
    detach
  endif
stop
@enduml

Enjoy, wink
Regards,
Th.
