很难找到在线文章，甚至在WP codex中，为主题选项在节内创建节。下面的屏幕截图显示了我正在尝试创建的内容：
我有下面创建这样的简单代码，但我不知道如何在节中创建节。任何帮助都将不胜感激，并帮助未来的开发人员。
function site_customize_register( $wp_customize ) {
/**
* section
*/
//so called "parent" section
$wp_customize->add_section("homepage_options",[
"title" => __("Homepage Options", "customizer_homepage_options_section"),
"priority" => 10,
]);
//so called "parent" section
$wp_customize->add_section("homepage_options_donate_now",[
"title" => __("Donate Now", "customizer_homepage_options_section"),
"priority" => 10,
]);
/**
* setting
*/
$wp_customize->add_setting("four_image_cta_block", [
"default" => "",
"transport" => "postMessage",
]);
$wp_customize->add_setting("four_image_cta_block_two", [
"default" => "",
"transport" => "postMessage",
]);
$wp_customize->add_setting("four_image_cta_block_three", [
"default" => "",
"transport" => "postMessage",
]);
$wp_customize->add_setting("four_image_cta_block_four", [
"default" => "",
"transport" => "postMessage",
]);
/**
* control
*/
$wp_customize->add_control(new WP_Customize_Control(
$wp_customize,
"four_image_cta_block",
[
"label" => __("First Item Link Text", "customizer_four_image_cta_block_label"),
"section" => "homepage_options",
"settings" => "four_image_cta_block",
"type" => "textarea",
]
));
$wp_customize->add_control(new WP_Customize_Control(
$wp_customize,

$wp_customize->add_control(new WP_Customize_Control(

似乎没有一种简单的方法可以做到这一点。环顾四周，我发现有两种方法可以做到这一点。
在我看来，第一种不太优雅的方法是将HTML注入到该部分的description 参数然后，您可以将一些JS连接到自定义HTML，使其按您想要的方式工作。
第二种方法是扩展内置WP_Customize_Control 类创建一个显示/隐藏另一组控件的控件。类似于
class Expand_Other_Control extends WP_Customize_Control{
public $type = \'button\';
protected $controlledElements = array();
public function __construct($manager, $id, $args = array()){
parent::construct($manager,$id,$args);
if( isset($args[\'settings\']) ){
$this->controlledElements = $args[\'settings\'];
//$this->settings may or may not be an array, we need it to be an array for our custom render function
is_array($this->controlledElements) or $this->controlledElements = array($this->controlledElements);
}
}
public function render_content(){
echo \'<button class="expand" data-elements="\'.json_encode($this->controlledElements).\'>Expand \'. $this->label . \'</button>\';
}
}
那么您可以这样使用它：
$wp_customize->add_control(
new Expand_Other_Control (
$wp_customize,
\'your_setting_id\',
array(
\'label\' => __( \'Button\'s Label\' ),
\'section\' => \'your_section_id\',
\'settings\' => \'your_setting(s)_id\',
)
)
);
请注意，这更像是一个即兴的概念验证。您仍然需要创建自己的JS来完成所有这些工作，这需要一些修改和验证。
