It seems the best practise when it comes to forms is to lay the fields out in a one column layout - should this be true for fields that are related to each other?
For example, would a suitable exception to this be First name / last name and date of birth? As they are commonly expressed on a single line, e.g:
[First name] [Last name]
[Gender]
[Job title]
[E-mail]
[DOB - Day][DOB - Month][DOB - Year]
Or would it still be optimal to do:
[First name]
[Last name]
[Gender]
[Job title]
[E-mail]
[DOB - Day]
[DOB - Month]
[DOB - Year]
And is there any research behind which ever is best?
