Idaho Code § 20-528

All orders or final judgments made by any court in matters affecting a juvenile offender within the purview of this act may be appealed by the juvenile offender or the state. A decision by the court pursuant to section 20-508, Idaho Code, not to waive jurisdiction under this act over the juvenile offender may be appealed by the state. Appeals shall be reviewed as provided by the appellate rules of the supreme court of Idaho, except no undertaking shall be required. Upon filing of the notice of appeal, the district court shall take jurisdiction of the case and if the juvenile offender is in detention shall promptly hold a hearing after the filing of a request to determine whether the juvenile offender shall remain in detention.
