understand this i choosed ticketcreate and its choices. Now the json will look like this .


{
  "TicketCreate": {
    "combinations": [
      {
        "isEnabled": true,
        "fields": {
          "status": "2",
          "priority": "2"
        }
      }
    ]
  }
}


 if i want another combo with same event, i will click addnewrule and choose ticketcreate, then choosing field and choices. it should add as new combination . now the json should view like this.


{
  "TicketCreate": {
    "combinations": [
      {
        "isEnabled": true,
        "fields": {
          "status": "2",
          "priority": "2"
        }
      },
      {
        "isEnabled": true,
        "fields": {
          "status": "4",
          "priority": "3"
        }
      }
    ]
  }
}




now in this mapping : how many combinations are there for a event, that much time you have to create event 

for example in this TicketCreate , combination -2, that means

1st set of dropdown - Event (Ticket Create) -  1st combination of fields and choices,  
   {
        "isEnabled": true,
        "fields": {
          "status": "2",
          "priority": "2"
        }


then 2nd set of dropdown - Event (Ticket Create) - 2nd set of combination of fields and choices 

  {
        "isEnabled": true,
        "fields": {
          "status": "4",
          "priority": "3"
        }
      }
