Hello all -
I see in the release notes that Vertical Pools & Lanes can now be rendered in Camunda Modeler as of 5.19.0.
But I can’t, for the life of me, figure out how to actually switch a pool from horizontal to vertical via the UI. (I was able to make the change by dinking with the XML and change isHoriztonal to false.)
Am I just being dense? Halp!
Hey, welcome back!
Looks like an interesting difference of terminology…
Looking through the Issue (linked to the Change Log), RENDER of a vertical pool was fixed, but MODELING in a Vertical Pool was not. See Vertical Pools and Lanes Modeling · Issue #507 · bpmn-io/bpmn-js · GitHub
So you’ll have to wait a little while longer.
I had a feeling that was the case. 
Thanks for the quick response.
Actually, the issue says that quite a lot of vertical modeling functionality is implemented already. It’s just not promoted in the UI.
You can try vertical modeling after performing some manual steps.
- Create a new model in Camunda Modeler.
- Place a pool in it.
- Switch to the XML view (bottom left button).
- Change the
isHorizontal attribute from true to false.
- Switch off the XML view.
Your pool will now be vertical. And most modeling functionality will work vertically. However, sub process modeling may still behave horizontally in some cases.
