Problemer med Javascript-menu
Fra : Jimmy Snedker


Dato : 11-09-03 10:52

Hej Alle!
Håber nogen kan hjælpe med dette problem:

Jeg har en javascript der fungerer på nogenlunde samme måde som
denne her (bare uden 'mapper'):
http://www.dynamicdrive.com/dynamicindex1/navigate1.htm

Problemet er: Når man åbner en af hovedmenuerne og klikker på
underlink og den nye side kommer frem - så "klapper" menu'en
sammen og man kan derved ikke se hvilke underlink man kom fra -
kan man undgå dette? Således at menu'en ikke klapper sammen

Med venlig hilsen

Jimmy Snedker
