Draw an editable list of instance ports. Port names are named as "[fieldName] [index]"
public static void InstancePortList(string fieldName, Type type, SerializedObject serializedObject, NodePort.IO io, XNode.Node.ConnectionType connectionType = XNode.Node.ConnectionType.Multiple);| Parameters | Summary |
|---|---|
| fieldName | Base fieldName of the instance ports. If points to the field name of a list, the list will be used as backing values. |
| type | Instance NodePort value type. |
| serializedObject | The serializedObject of the node. |

| connectionType | Connection type of added instance ports |
