ユーザーがクイズで 2 つのリストの要素を接続する必要がある Web ページを作成しています。たとえば、国と首都の 2 つのリストがあり、ユーザーが首都を正しい国に接続する必要があるクイズの質問を想像してみてください。

できれば、ユーザーが要素を 2 番目のリストから最初のリストの要素の隣の領域にドラッグする方法が必要です。このような：

ここでは、青いボックスを灰色の長方形にドラッグします。

すでにこのようなことを行う jQuery プラグインまたは他の JavaScript ライブラリはありますか? それとも、自分で実装する必要がありますか? もしそうなら、誰かが同様の問題の解決策を説明している記事へのポインタ、またはこれを最もよく解決する方法についてのアイデアを持っていますか?

jQuery UI droppableの使用を検討していますか? それはあなたが望むことをほとんど行います。灰色のボックスをドロップ可能に、青色のボックスをドラッグ可能に設定するだけです。

おそらくrevert オプションを使用するでしょう。

このドラッグ アンド ドロップ Javascript コードは、ブラウザでは機能しますが、ipad の ibook アプリでは機能しません。jquery.ui.touch-punch.min.js を使用した場合でも解決策を教えてください。
