テキスト入力の上にオートコンプリートの結果セットを表示する方法はありますか？
問題は、lighboxアプリケーションで使用していることです。背景要素はページの高さと幅の100％に設定されているため、コンテンツとともに拡大することはありません。したがって、テキストボックスの上のコンテンツが非常に多くなり、入力がページの下部に向かって強制され、ユーザーがそれに何かを入力すると、オートコンプリートメニューが表示され、入力がページの終わりに向かっている場合、メニュースクロールバーが表示されます
背景要素（暗い色）はそれに対応するように拡張されないため、メニューは絶対に配置されているため、ページの下部が白（実際のページの色と一致）に見え、ページの上部が暗いように見えます。 。
とにかくこれを達成するために、オートコンプリートメニューが表示される前に、入力の位置をチェックする必要があります。たとえば、上から300ピクセル以上の場合、メニューは入力の上に表示されますか？これはコードです：
