Citizen Space allows you to select whether you would like to create a linear or non-linear online survey consultation.
A linear consultation contains pages in a specified order. Respondents complete the online survey in order, page by page from 1 to x, selecting 'Next' at the bottom of each page to move to the next page of questions. You must use a linear consultation if you want to set Skip Logic rules.
A non-linear consultation has an automatically generated ‘contents page’ as the first page after the overview. This structure is appropriate for e.g. long and detailed consultation documents, and consultations in which only certain sections of the consultation document may be relevant to a respondent. Respondents can pick and choose which area of the consultation they wish to respond to, and in which order. Respondents save and return to the contents after each page (or chapter) of questions they answer.
Two good examples of non-linear consultations can be seen on our demo site:
An example of a non-linear consultation's content page is shown below:
If you choose a non-linear survey structure, then you can add introductory text to the contents page (which can include snazzy stuff like images, PDF embeds and rich media) via the Online Survey Settings.
