Customizer控件中的多个输入

说我有一个自定义控件，但是此控件有2个需要保存的输入，例如：

• 货币类型和价值
• 尺寸和计量单位
• 名字和姓氏
• 文字和样式
• 图像和图像尺寸
• 字体家族和字体粗细

我该怎么办？我看到创建控件时有一个设置选项，但是没有文档说明如何使用它，而在野外完成它的唯一示例是Easy Google Fonts，它没有关于如何完成它的解释，以及很难读。是否可以嵌套控件和节？

到目前为止，我发现的所有教程和文档都讨论了具有单个html输入的控件，尽管API提出了建议，但都没有提及具有多个输入/设置的控件

这个插件演示了如何做到这一点。值得注意的是，涉及的步骤是：

• 注册每个设置以更新/更改
• 创建控件时，将数组作为设置参数
• 渲染输入时，传递设置键以链接和值
• 设置键不是设置的名称，而是数组的索引，例如0、1、2
• 通过访问访问注册到控件的设置 $this->settings

这是代码：
