Skrypt ten dzia│a pod Netscapem Navigatorem 4.x oraz Microsoft Explorerem 4.x.

Rozwijalna lista polega na stworzeniu skryptu ukrywaj╣cego czΩ£µ strony do momentu gdy naci£niemy przycisk.Aby zaprezentowaµ ten skrypt musimy stworzyµ plik o nazwie np: przyklad.html i umieszczamy w nim poni┐szy kod miΩdzy znacznikami <HEAD> </HEAD>:
