Hi,
I have read several articles but none of the proposed solutions work for me.
I am trying to add a new option to a cascading multi select list; I know how to get the fieldID and the contextID.
doing a POST /rest/api/3/field/${this.customFields[0].id}/context/${context.values[0].id}/option adds a new option to the 1st level but how to 1 add a new value to the 2nd level ?
Thanks for helping
Guido
