Progressive revealing. When implemented well, progressive revealing gives interactive forms a head start over traditional paper forms. When asked a particular question in a form it may be the case that, depending a users response, they are asked a set of specific sub-questions, or alternatively routed to the next appropriate section of the form.
People from different cultures have different conventions for answering seemingly innocuous questions like this. Users will become frustrated if when you ask for an email address, for example, if the response box only allows for 20 characters.
See our Guidance notes, page 6, paragraph 2. When filling in your forms people want the information they need there and then. Put yourself in the form users position and think about which questions they might have a problem with. Provide examples of the sorts of answers you are looking for, and where appropriate, provide guidance notes as near as possible to the question they relate to (i.e. in the actual form).
In paper forms the specific sub-questions cannot be hidden from the user when they are not relevant to them - but in interactive forms this is relatively easy to do. Use progressive revealing as much as possible in your form design to shield your users from questions they do not need to see.
