最终目标是在 Wordpress 中为 Elementor 提供一个小部件，该小部件可以在选项卡内创建多个按钮。所以我想要一个中继器内部的中继器。
我还没有所有的功能或样式，只是列出页面上每个输入的非常基本的设置。我的代码不起作用。该插件正确显示，但是所有元素或控件都消失了。
这是代码：
<?php
namespace Elementor;
if ( ! defined( 'ABSPATH' ) ) {
exit; // Exit if accessed directly.
}
/**
* Elementor iatabs widget.
*
* Elementor widget that displays vertical or horizontal iatabs with different
* pieces of content.
*
* @since 1.0.0
*/
class Widget_AltTabs extends Widget_Base {
/**
* Get widget name.
*
* Retrieve iatabs widget name.
*
* @since 1.0.0
* @access public
*
* @return string Widget name.
*/
public function get_name() {
return 'alttabs';
}
/**
* Get widget title.
*
* Retrieve tabs widget title.
*
* @since 1.0.0
* @access public
*
* @return string Widget title.
*/
public function get_title() {
return __( 'AltTabs', 'elementor' );
}
/**
* Get widget icon.
*
* Retrieve tabs widget icon.
*
* @since 1.0.0
* @access public
*
* @return string Widget icon.
*/
public function get_icon() {
return 'eicon-tabs';
}
protected function _register_controls() {
$this->start_controls_section(
'content_section',
[
'label' => __( 'Content', 'elementor' ),
'tab' => Controls_Manager::TAB_CONTENT,
]
);
$this->add_control(
'list',
[
'label' => __( 'Repeater List', 'elementor' ),
'type' => Controls_Manager::REPEATER,

);
$this->end_controls_section();

Plugin::instance()->widgets_manager->register_widget_type( new Widget_AltTabs ); ?>这是我收到的错误消息的示例：

我对编写 Elementor 小部件/插件还很陌生，所以我被难住了。我将不胜感激任何帮助。谢谢！
