In a mobile web form is not a good idea to place a long dropdown lists, for both usability and to avoid problems on old mobile phones.
This is confirmed at http://wiki.forum.nokia.com/index.ph...rop-down_menul
“If the list of options within the menu is long, there may not be enough vertical space to display all options and the user may therefore have to scroll. On touch devices, scrolling may be particularly difficult as the scroll bar may be too small to properly grasp.”

I would like to know your experience and opinions on this.
Which do you think is the best alternative to a long dropdown lists, like a list of cities, on a mobile web form with several fields?
