Thank you for your inquiry. I’m sorry that currently these subprocess properties only available in our desktop version. We will consider to support them in our online version in future. Feel free to contact me for any questions and wish you have a good day!
I would like to let you know we now support Ad-hoc, Compensation & Transaction property for sub-process in our online business process diagram. You can find these properties under the Setting Panel > Style of the sub-process element. Feel free to contact me for any help and wish you have a good day!
