Change question order/ja
From LimeSurvey Manual
グループ内での質問の順序を変更するには、グループボタンバーの「質問の順序を変更」ボタン を押します。(このボタンはグループ内に質問が2つ以上ある時だけ表示されます。)
順序変更画面では、回答者に提示される順番で質問が表示されます。「上へ」「下へ」ボタンを押せば、順番を変更できます。
If you set conditions on question the particular condition might prevent re-ordering a question before/after another question. In that case you will have to delete/change that condition first.
Starting in Version 1.92: You can always re-order questions and groups, even if there are conditions. You don't need to delete conditions. This is because Expression Manager converts any conditions you enter via the Conditions Editor into a Relevance Equation, and is able to detect whether you have used any variables before declaring them (such as via the Show Logic File button)
