Additional categories to Event Category field + adding field to the Event Pop Up form and Com list

Hello All,

How to add additional options to Event Category. When adding via Customize Form > Options, I am having the below error.

I have also added a second field named “Additional Event Category” via Customize Form for event, however I am unable to add the second field in the Event pop up form and the Communication list. Kindly help on this issue


Please check the reference:


I have been able to add the additional categories via property setter.

I have also added the same categories to the communication medium via property setter

However when creating a new event, it is not appearing in “Type” in the communication list , can you please advise?

Development is needed! It’s not easily set.
