我创建了一个儿童主题。父主题使用Foundation Framework。我还将foundation framework加入到我的孩子主题中，并尝试添加一个带有下拉菜单的简单导航栏，但下拉菜单似乎不是下拉菜单。这是我的功能。php

<?php
add_action( \'wp_enqueue_scripts\', \'_my_child_theme_styles\', PHP_INT_MAX );
/**
 * Enqueue parent theme styles considering styles dependencies.
 */
function _my_child_theme_styles() {
    // Parent styles that need to be loaded before the child theme styles.
    $parent_styles = array(  \'parent_style_1\' => \'style.css\', \'parent_style_2\' => \'styles/modern.css\' );
    // Enqueue parent styles using the custom handles and considering styles dependencies.
    foreach( $parent_styles as $handle => $style ) {
        wp_enqueue_style( $handle, get_template_directory_uri() . \'/\' . $style, array( \'hrb-normalize\', \'hrb-foundation\' ) );
    }

    wp_enqueue_style( \'child-style\',
        get_stylesheet_directory_uri() . \'/style.css\',
        array_keys( $parent_styles )
    );


}
