我想创建一个elementor小部件，并将其添加到基本的elementor菜单中。我根据本教程找到并执行此操作，但它不起作用(不出现在基本菜单中(：https://develowp.com/build-a-custom-elementor-widget/在此处输入图像描述。我使用调试，我认为原因可能是以下代码："add_action('elementor/widgets/widgets_registered'，[$this，'register_widgets'](；"有人能帮我解决这个问题吗？或者有人能正确运行其他代码吗？

**创建自定义Elementor Widget与创建本地WordPress小部件没有太大区别，基本上是从创建一个扩展Widget_Base类的类开始，并填充所有所需的方法。

每个小部件都需要有一些基本设置，比如在代码中识别小部件的唯一名称、用作小部件标签的标题和图标。除此之外，我们还有一些高级设置，如小部件控件，这些控件基本上是用户选择自定义数据的字段，以及基于小部件控件中的用户数据生成最终输出的渲染脚本。**
