I would like to be advised on the best presentation (appearance parameter) of the data when using a select_one and the entry is made on a mobile phone (Android)
May depend partly on the length of the choice list, the content and the page design.
- Short lists, fitting even on one middle-size screen, I would keep all visible (i.e. no special appearance).
- For longer lists, we normally also use no appearence. We prefer that a user can easily scroll down in the whole list. And it seems more robust against tick errors.
Sometimes we add grouping lines, like *** Africa *** in very long country list. We give them systematic choice names like ‘-100’ ‘-200’, to constraint them by regex against final selection.
A disadvantage using apperance for us is, that you will not see the list if you print a form (or submission). (We print the empty form as paper backup for field work, in case of IT problems.)
Furthermore, it depends on whether
you use group-list for questions. Where you want to have more then one question on a screen, you may prefer a condensed choice list appearence.
Finally, you might also discuss the options with your users, even for different form parts, esp. between full list and search option.
Thank you for your help!
