我使用 WPBakery 的 API 开发了一个插件，它基本上允许用户选择帖子类型，以及要在前端显示的分类。我想要实现的是动态显示附加字段的能力，这取决于首先选择哪个父分类。

例如，我在一个多下拉字段中显示所有父分类。根据选择的分类法，然后我想显示其他下拉列表，其中这些分类法的子级作为选择。

在这一点上，我觉得我唯一的解决方案是输出大量动态命名的字段（就像在每个父分类的每个子术语中一样），并使用一些 JavaScript 来显示/隐藏那些被选为下拉列表的字段。这似乎是一个糟糕的实现，DOM 中有过多的 HTML（尽管是隐藏的）。

我也考虑过将参数注入 DOM，但我不完全确定如何在后端处理它们，因为它们可能没有注册。

有一个param_group，但它似乎用于转发器字段，而不是动态人口。

我的代码如下所示：

function YYY() {

  add_shortcode('YYY', 'YYY');

  $markup = 'YYY';

  $types = get_post_types([], 'array');
  $post_types = array("All");
  foreach($types as $type) {
    $post_types[] = $type - > name;
  }

  $taxonomies = get_taxonomies();

  foreach($taxonomies as $taxonomy) {
    $post_taxonomies[] = $taxonomy;
  }

  vc_map(array(
    "name" => __("YYY"),
    "base" => "YYY",
    "category" => __('Content'),
    "custom_markup" => $markup, // @TODO how do we access shortcode's attributes here to display in bakery grid
    "params" => array(
      array(
        'type' => 'dropdown_multi',
        'heading' => __('Select a post type', VAE_TEXT_DOMAIN),
        'param_name' => 'post_types',
        'value' => $post_types,
        'description' => __('Select a post type', VAE_TEXT_DOMAIN),
        'admin_label' => false,
        'save_always' => true,
      ),
      array(
        "type" => "dropdown_multi",
        "holder" => "div",
        "class" => "",
        "heading" => __("Count"),
        "param_name" => "count",
        "value" => array("All", "3", "6"),
        "description" => __("How many tiles to show")
      ),
      array(

        "value" => $taxonomies,

dependency事实证明，使用如下参数非常简单：

array(
         "type" => "dropdown_multi",
         "holder" => "div",
         "class" => "",
         "heading" => __("Select Category(ies)"),
         "param_name" => "categories",
         "value" => $post_categories,
         "description" => __("Posts with selected categories will be shown"),
         "dependency" => array(
            "element" => 'taxonomies',
            'value' => 'category'
         )
      )
