Example:

import enumeratum.values.StringEnum
import enumeratum.values.StringEnumEntry

sealed trait FirstLevel extends StringEnumEntry

object FirstLevel extends StringEnum[FirstLevel] {

  case object One extends FirstLevel {
    val value = "one"
  }
  case object Two extends FirstLevel {
    val value = "two"
  }

  sealed trait SecondLevel extends FirstLevel

  case object Three extends SecondLevel {
    val value = "three"
  }

  override def values: IndexedSeq[FirstLevel] = findValues

}
