Nav walker、ブートストラップ:2nd levelの下に3rd levelアイテムを表示

ドロップダウンメニューにWP_bootstrap_navwalkerを使用しています。これはうまくいきますが、それは私に最初と2番目のレベルのアイテムを表示するだけです。そのため、最初のレベルのドロップダウンと、ドロップダウンが開いているときの通常の2番目のアイテム。 3番目のレベルは見えません。

私は2番目のレベルの項目の下にそれを表示したいです。ウォーカーは現在、それを他のドロップダウンにしています(それは機能しません)。

私は自分のニーズに合うように適切にウォーカーを編集するのに十分熟練していません。誰かが私を助けることができますか?

ウォーカーコード:

私はこの問題を解決しました。これらの指示に従ってください.....

  1. スクリプトを追加

(function($){ $(document).ready(function(){ $('ul.dropdown-menu [data-toggle=dropdown]').on('click', function(event) { event.preventDefault(); event.stopPropagation(); $(this).parent().siblings().removeClass('open'); $(this).parent().toggleClass('open'); }); }); })(jQuery);

2.次の行から&& $depth === 0を削除します。wp_bootstrap_navwalker.phpファイルのif ( $args->has_children && $depth === 0 )

スクリーンショットを見る here

あなたが削除する必要があります

&& 0 === $depth

オンラインで

$item_output .= ( $args->has_children && 0 === $depth ) ? ' <span class="caret"></span></a>' : '</a>';

そのため、キャレットはメニューのテキストの横に表示されます。
