(a) A court of this State which has jurisdiction under this Act to make a child-custody determination may decline to exercise its jurisdiction at any time if it determines that it is an inconvenient forum under the circumstances and that a court of another state is a more appropriate forum. The issue of inconvenient forum may be raised upon motion of a party, the court’s own motion, or request of another court.
     (b) Before determining whether it is an inconvenient forum, a court of this State shall consider whether it is appropriate for a court of another state to exercise jurisdiction. For this purpose, the court shall allow the parties to submit information and shall consider all relevant factors, including:
