Magento 2 How to get disable/enable child categories?

Question

I am working with display all categories on a custom page, either it is enabled or disabled.

When I try to get child categories with "getChildrenCategories()", but it is returning only enabled child categories it is not returning the disabled child categories. I need both types of child categories.

How can I get the all child categories which are disabled/enabled?

please check the code as below.

protected $_categoryFactory;
public function __construct(
\Magento\Backend\App\Action\Context $context,
\Magento\Catalog\Model\CategoryFactory $categoryFactory
){
    parent::__construct($context);
    $this->_categoryFactory = $categoryFactory;
}

public function getAllChildCategories($categoryId)
{
    $categoryObj = $this->_categoryFactory->create()->load($categoryId);
    if($categoryObj->hasChildren()) {
        return $categoryObj->getChildrenCategories();
    }

}

Default children categories only return as active. You need to that function changes to get the categories that you want to override.

vendor/magento/module-catalog/Model/ResourceModel/Category.php

From

public function getChildrenCategories($category)
{
    $collection = $category->getCollection();
    /* @var $collection \Magento\Catalog\Model\ResourceModel\Category\Collection */
    $collection->addAttributeToSelect(
        'url_key'
    )->addAttributeToSelect(
        'name'
    )->addAttributeToSelect(
        'all_children'
    )->addAttributeToSelect(
        'is_anchor'
    )->addAttributeToFilter(
        'is_active',
        1
    )->addIdFilter(
        $category->getChildren()
    )->setOrder(
        'position',
        \Magento\Framework\DB\Select::SQL_ASC
    )->joinUrlRewrite();

    return $collection;
}

To

public function getChildrenCategories($category)
{
    $collection = $category->getCollection();
    /* @var $collection \Magento\Catalog\Model\ResourceModel\Category\Collection */
    $collection->addAttributeToSelect(
        'url_key'
    )->addAttributeToSelect(
        'name'
    )->addAttributeToSelect(
        'all_children'
    )->addAttributeToSelect(
        'is_anchor'
    )->addIdFilter(
        $category->getChildren()
    )->setOrder(
        'position',
        \Magento\Framework\DB\Select::SQL_ASC
    )->joinUrlRewrite();

    return $collection;
}

From the above functions remove "is_active" filter too that function

Please try with below code.

public function __construct(
        Template\Context $context, 
        \Magento\Catalog\Model\Layer\Resolver $layerResolver, 
        \Magento\Framework\Registry $registry, 
        \Magento\Catalog\Helper\Category $categoryHelper, 
        \Magento\Catalog\Model\CategoryFactory  $categoryFactory,
        array $data = array()) 
    {
        parent::__construct($context, $layerResolver, $registry, $categoryHelper,$data);
        $this->_categoryFactory = $categoryFactory;
        $this->_collectionFactory = $collectionFactory;
     }

    public function getCategoryList()
    {
      $_category  = $this->getCurrentCategory();
      $collection = $this->_categoryFactory->create()->getCollection()->addAttributeToSelect('*')
              ->setOrder('position', 'ASC')
              ->addIdFilter($_category->getChildren());
      return $collection;

    }

I hope its work for you.
