+## What
+
+This feature lets form creators ask form fillers to enter an answer if they’ve selected ‘none of the above’ from a selection list question.
+
+Form creators can choose whether it’s mandatory or optional for form fillers to provide an answer if they’ve selected ‘none of the above’.
+
+## Why
+
+It’s a requested feature that people expect a form builder to have. We expect it to increase the number of forms and submissions, and to have a positive impact on user satisfaction.
+
+At least 5 departments had expressed interest in this feature. We’d also received at least 5 anonymous feedback tickets about it from our feedback link by the time we started the work.
+
+The need for this feature came up as part of the ‘select from a long list’ work, as we were adding a ‘None of the above’ option to autocomplete.
+
+Usability testing suggested that some people expected to be able to add an option for ‘Other’ followed by a text box where they could enter more information.
