wp_nav_menu 更改子菜单类名称? [英] wp_nav_menu change sub-menu class name?

问题描述

有没有办法将 WordPress 本身生成的子 <ul class="sub-menu"> 更改为自定义类名?

Is there a way to change the child <ul class="sub-menu"> generated by WordPress itself to a custom class name?

我知道父

您可以使用 'menu_class' => 删除或更改名称.'新名称'.

I know the parent <ul> you can remove or change the name with 'menu_class' => 'newname'.

我找不到答案.Itried 'submenu_class' =>'自定义名称'.这对我来说似乎是合乎逻辑的，但显然这不是正确的.

I couldn't find the answer. Itried 'submenu_class' => 'customname'. It seems logic to me, but obviously that is no the right one.

有什么想法吗?

推荐答案

对此没有选项，但您可以扩展 WordPress 用于创建菜单 HTML 的walker"对象.只需要覆盖一种方法:

There is no option for this, but you can extend the 'walker' object that WordPress uses to create the menu HTML. Only one method needs to be overridden:

class My_Walker_Nav_Menu extends Walker_Nav_Menu {
  function start_lvl(&$output, $depth) {
    $indent = str_repeat("\t", $depth);
    $output .= "\n$indent<ul class=\"my-sub-menu\">\n";
  }
}

然后，您只需将 walker 的实例作为参数传递给 wp_nav_menu，如下所示:

Then you just pass an instance of your walker as an argument to wp_nav_menu like so:

'walker' => new My_Walker_Nav_Menu()
