我正在尝试将HTML站点重新开发为Wordpress主题，HTML菜单如下：

<ul>
    <li class="current"><a href="#"><div>Home</div></a></li>
    <li><a href="#"><div>Link 1</div></a>
        <ul>
            <li><a href="#"><div class="flintstone-nav">Sublink 1</div></a></li>
            <li><a href="#"><div class="flintstone-nav">Sublink 2<br><div class="flintstone-nav-small">Smaller Text</div></div></a></li>
            <li><a href="#"><div class="flintstone-nav">Sublink 3<br><div class="flintstone-nav-small">Smaller Text</div></div></a></li>
        </ul>
    </li>
</ul>

我已经删除了默认菜单包装器和默认菜单类，并使用以下内容声明了一个自定义导航菜单遍历器：

<?php wp_nav_menu( array( \'container\' => \'false\', \'menu_class\' => \'\', \'items_wrap\' => \'%3$s\', \'theme_location\' => \'header-menu\', \'walker\' => new themeslug_walker_nav_menu ) ); ?>

我的步行者是这样的：

class themeslug_walker_nav_menu extends Walker_Nav_Menu {

// add classes to ul sub-menus
function start_lvl( &$output, $depth = 0, $args = array() ) {
    // depth dependent classes
    $indent = ( $depth > 0  ? str_repeat( "\\t", $depth ) : \'\' ); // code indent
    $display_depth = ( $depth + 1); // because it counts the first submenu as 0
    $classes = array(
        \'sub-menu\',
        ( $display_depth % 2  ? \'menu-odd\' : \'menu-even\' ),
        ( $display_depth >=2 ? \'sub-sub-menu\' : \'\' ),
        \'menu-depth-\' . $display_depth
        );
    $class_names = implode( \' \', $classes );

    // build html
    $output .= "\\n" . $indent . \'<ul>\' . "\\n";
}

// add main/sub classes to li\'s and links
 function start_el(  &$output, $item, $depth = 0, $args = array(), $id = 0 ) {
    global $wp_query;
    $indent = ( $depth > 0 ? str_repeat( "\\t", $depth ) : \'\' ); // code indent

    // depth dependent classes
    $depth_classes = array(
        ( $depth == 0 ? \'main-menu-item\' : \'sub-menu-item\' ),
        ( $depth >=2 ? \'sub-sub-menu-item\' : \'\' ),
        ( $depth % 2 ? \'menu-item-odd\' : \'menu-item-even\' ),
        \'menu-item-depth-\' . $depth
    );
    $depth_class_names = esc_attr( implode( \' \', $depth_classes ) );

    // passed classes
    $classes = empty( $item->classes ) ? array() : (array) $item->classes;
    $class_names = esc_attr( implode( \' \', apply_filters( \'nav_menu_css_class\', array_filter( $classes ), $item ) ) );

    // build html
    $output .= $indent . \'<li class="\' . $class_names . \'">\';

    // link attributes
    $attributes  = ! empty( $item->attr_title ) ? \' title="\'  . esc_attr( $item->attr_title ) .\'"\' : \'\';
    $attributes .= ! empty( $item->target )     ? \' target="\' . esc_attr( $item->target     ) .\'"\' : \'\';
    $attributes .= ! empty( $item->xfn )        ? \' rel="\'    . esc_attr( $item->xfn        ) .\'"\' : \'\';
    $attributes .= ! empty( $item->url )        ? \' href="\'   . esc_attr( $item->url        ) .\'"\' : \'\';
    $attributes .= \' class=""\';

    $item_output = sprintf( \'%1$s<a%2$s><div>%3$s%4$s%5$s</div></a>%6$s\',
        $args->before,
        $attributes,
        $args->link_before,
        apply_filters( \'the_title\', $item->title, $item->ID ),
        $args->link_after,
        $args->after
    );

    // build html
    $output .= apply_filters( \'walker_nav_menu_start_el\', $item_output, $item, $depth, $args );
}
}

正如您在HTML菜单上所看到的，锚定中有div，我已经设法将它们插入到$item_output . 但是有一些div在子菜单锚定中有类，如何将类仅在子菜单项上放入div？

不用担心Wordpress菜单项标题字段中的小文本div，我相信它可以接受HTML，这只是在菜单项标题下出现几个单词。

提前感谢您的帮助。

$format = \'%1$s<a%2$s><div>%3$s%4$s%5$s</div></a>%6$s\';
if( $depth > 0 ) $format = \'%1$s<a%2$s><div class="flintstone-nav">%3$s%4$s%5$s</div></a>%6$s\';
$item_output = sprintf( $format,
        $args->before,
        $attributes,
        $args->link_before,
        apply_filters( \'the_title\', $item->title, $item->ID ),
        $args->link_after,
        $args->after
    );
