只是想知道是否有人可以帮助我将代码添加到WordPress 4.7.4导航菜单中的现有菜单助手中,该菜单名为" main"在所有顶级项目的A链接中添加页面标题周围的范围。
我希望(简化的)html看起来像这样:
<ul>
<li><a href="#" title="Page 1"><span>Page 1</span></a></li>
<li><a href="#" title="Page 2"><span>Page 2</span></a><div class="drop">
<ul>
<li><a href="#" title="Sub Page 2.1">Sub Page 2.1</a></li>
<li><a href="#" title="Sub Page 2.2">Sub Page 2.2</a></li>
<li><a href="#" title="Sub Page 2.3">Sub Page 2.3</a></li>
<li><a href="#" title="Sub Page 2.4">Sub Page 2.4</a></li>
</ul>
</div></li>
<li><a href="#" title="Page 3"><span>Page 3</span></a></li>
<li><a href="#" title="Page 4"><span>Page 4</span></a><div class="drop">
<ul>
<li><a href="#" title="Sub Page 4.1">Sub Page 4.1</a></li>
<li><a href="#" title="Sub Page 4.2">Sub Page 4.2</a></li>
</ul>
</div></li>
<li><a href="#" title="Page 5"><span>Page 5</span></a></li>
<li><a href="#" title="Page 6"><span>Page 6</span></a></li>
<li><a href="#" title="Page 7"><span>Page 7</span></a></li>
</ul>
我的functions.php文件中的walker当前包含代码,用于在下拉菜单的子菜单项周围添加包装div。这很有效,如下所示:
class main_menu_walker extends Walker_Nav_Menu
{
function start_lvl(&$output, $depth = 0, $args = array())
{
$indent = str_repeat("\t", $depth);
$output .= "\n$indent<div class=\"drop\"><ul>\n";
}
function end_lvl(&$output, $depth = 0, $args = array())
{
$indent = str_repeat("\t", $depth);
$output .= "$indent</ul></div>\n";
}
}
菜单调用中的Link_before和link_after属性似乎不合适,因为它们会向所有菜单项(包括子页面)添加跨度。
我发现了一些用于在顶级项目周围添加跨度的functions.php代码,但这会为所有WP菜单的顶级项目添加跨度,而不仅仅是名为&#34; main&#34;的菜单。此代码如下所示:
add_filter( 'wp_nav_menu_objects', function( $items ) {
foreach ( $items as $item ) {
if (!$item->menu_item_parent) {
$item->title = '<span>' . $item->title . '</span>';
}
}
return $items;
});
以上代码是否可以在名为main的一个菜单的菜单步进器内工作?如果是这样,我该如何实现?或者是菜单步行者需要新代码?如果是这样,有什么想法吗?
提前感谢您的帮助。

嘿,我按照我的项目实现了一个代码,菜单html是相同的。
希望这会对你有所帮助: - )
检查下面的HTML代码
<nav class="wsmenu slideLeft clearfix">
<ul class="mobile-sub wsmenu-list">
<li><a href="index.html" class="active"> Menu 1</a></li>
<li><a href="services.html">Menu 2 <span class="arrow"></span></a>
<ul class="wsmenu-submenu">
<li><a href="#"> sub Menu 2</a>
<ul class="wsmenu-submenu-sub">
<li><a href="#">sub sub Menu 2</a></li>
<li><a href="#">sub sub Menu 2</a></li>
<li><a href="#">sub sub Menu 2</a></li>
</ul>
</li>
<li><a href="#">sub Menu 2</a>
<ul class="wsmenu-submenu-sub">
<li><a href="#">sub sub Menu 2</a></li>
<li><a href="#">sub sub Menu 2</a></li>
<li><a href="#">sub sub Menu 2</a></li>
</ul>
</li>
<li><a href="#">Onsite Gear Measurement</a></li>
</ul>
</li>
<li><a href="">Menu 3</a></li>
<li><a href="">Menu 4</a></li>
</ul>
</nav>
检查Header.php文件中的Header菜单代码
<nav class="wsmenu slideLeft clearfix">
<!--<ul class="mobile-sub wsmenu-list">-->
<?php
wp_nav_menu( array( 'theme_location' => 'primary',
'menu_class' => 'mobile-sub wsmenu-list',
'menu_id' => '',
'container' => false,
'walker' => new WPDocs_Walker_Nav_Menu()) );
?>
</nav>
检查以下代码中的walker菜单放在function.php文件中

function start_lvl( &$output, $depth = 0, $args = array() ) {
// Depth-dependent classes.
