スライドの上下のメニュー onclick 用にこのコードをダウンロードしました。これは正常に動作します。サブメニューを2回非表示にする必要があります。つまり、最初にクリックするとサブメニューが開き、同じメニューを次にクリックするとサブメニューが非表示になりますが、これはできません。提案をお願いします。

あなたのスキルのレベルに応じて、ダウンロードしたコードを廃棄します。構成を説明するのは非常に複雑なようです。これを複数の場所でさまざまな方法で使用する必要がない場合。css とクラスでドロップダウンのすべての状態を処理し、jquery でクリック イベントの委任を処理します。たとえば、「.open-drop-down」のクラスを作成して、クリックされた任意の要素に適用できます。一度に 1 つのドロップダウンのみを開きたい場合は、新しいドロップダウンを開く前に開いているドロップダウンをクリアします。次のようにして、これを簡単に行うことができます。

$('#drop-down-menu li').removeClass('open-drop-down');

開いているメニュー タブを閉じるには、クリック イベントの上部で次のようなチェックを行うことができます。

if ($(this).is('.open-drop-down') {
     $(this).removeClass('open-drop-down');
     return;
}

これにより、クリックした要素 ( $(this) ) に「open-drop-down」のクラスがあるかどうかがチェックされ、そのクラスが削除されて返されるため、残りの関数は実行されません。

基本関数の例:

$('#drop-down-menu').on('click', 'li', function(e) {
    e.preventDefault()
    if ($(this).is('.open-drop-down')) {
        $(this).removeClass('open-drop-down');
        return;
    }
    $('#drop-down-menu li').removeClass('open-drop-down');
    $(this).addClass('open-drop-down')
});

これは、すべての視覚的側面が css で処理されることを前提としています。必要に応じて、remove および add クラス関数の 2 番目のパラメーターを使用して、アニメーションを追加できます。

これは私の意見にすぎませんが、ドロップダウンにはこれだけの jquery コードで十分です。

要素の 2º クリックを確認する方法を見つけてみてください。例えば：
