Es realmente difícil ser preciso sobre cuánto desplazarse para llegar al final del menú desplegable. Lo que suele ocurrir es que me paso de desplazamiento y el cuerpo principal comienza a moverse.
Estaba pensando si querríamos deshabilitar el desplazamiento en el cuerpo cuando el menú desplegable está activo, o al menos cuando el mouse está sobre el menú desplegable.
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
