É realmente difícil ser preciso sobre quanto rolar para chegar ao final do menu suspenso. O que geralmente acaba acontecendo é que eu rolo demais e o corpo principal começa a rolar.
Estava pensando se seria desejável desabilitar a rolagem no corpo quando o menu suspenso estiver ativo ou, pelo menos, quando o mouse estiver sobre ele.
This is more obvious on iPhone and Android mobile devices.
And separately:
I’ve even seen some iPhone devices scroll the page randomly even though not at the bottom or top of the menu scroll - but this was with some site customisations.
I believe this problem might have been mentioned in this Gotcha video by Paul @ 2m15s from back in January:
It starts with “Did you know you can’t stop the body from scrolling?”…
… he mentions there is something coming along the pipeline in “spec land” - but there is now way currently of controlling it.
Obviously - there might be something now because that was 6 months ago.
P.S. other parts of the video are interesting too, worth a watch
