WordPressでdrawer.js実装

CDN読み込み

公式サイト:
https://git.blivesta.com/drawer

▼一部参考

公式サイトよりCDNの記述をコピーしてheadタグ内に張り付け

▼functions.php

<?php
add_action('wp_head', function () {
?>
<!-- drawer.css -->
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/drawer/3.2.2/css/drawer.min.css">

<!-- bootstrap(ドロップダウンメニューにするなら必要) -->

});

各ファイルマークアップ

        ) ); ?>
    </nav>
    </header>
    <main role="main">

下記サイトを参考にナビゲーションメニューの要素にクラス付与

▼functions.phpに追記

  1. ナビゲーションメニューの要クラス付与のためのフィルターイベント
  2. スタイル調節のためのCSS
  3. Drawerを動かすために、jQueryのコード
// wp_nav_menuのliにclass追加
function add_additional_class_on_li($classes, $item, $args)
{
if (isset($args->add_li_class)) {
$classes['class'] = $args->add_li_class;
}
return $classes;
}
add_filter('nav_menu_css_class', 'add_additional_class_on_li', 1, 3);

// wp_nav_menuのaにclass追加
function add_additional_class_on_a($classes, $item, $args)
{
if (isset($args->add_li_class)) {
$classes['class'] = $args->add_a_class;
}
return $classes;
}
add_filter('nav_menu_link_attributes', 'add_additional_class_on_a', 1, 3);

add_action('wp_head', function () {
?>
