QS:Other comment mandatory
From LimeSurvey Manual
'その他' 欄への入力必須 (other_comment_mandatory)
説明
"その他"オプション付きで回答必須の質問にのみ適用され、回答者に自由文回答（"その他コメント"）を入力させるものです。
オンにすると、アンケート参加者がその他（チェックボックスまたはリスト）を選択した場合、"その他コメント"にコメントを入力しないと先に進めなくなります。
Note that this option is not available for Multiple Choice questions because the "Other" checkbox status is not recorded in the database for this question type, only the content being recorded. This means that checking the "other" checkbox is just a visual effect that is only meaningful if the text box is filled in: that is why other_comment_mandatory is assumed to be set for this question type.
Available options
- On
- Off (default)
Example
If activated for a "Multiple options with comments" question and the user enters a value in the left part of the Other answer but doesn't enter text in the Other Comment part, a warning message will be displayed when he tries to proceed to the next page.
