如何获取将“包含在导航菜单中”设置为否的所有子类别的列表

我试图获取所有未包含在导航菜单中但仍处于活动状态的子类别，这些类别位于列表页面中。

$children = Mage::getModel('catalog/category')->getCategories(10); //10 current category id

即使此类别集合也仅返回导航菜单中包含的子类别。

如何获取导航菜单中未包含的类别？

尝试这个：

$collection = Mage::getResourceModel('catalog/category_collection')
    ->addAttributeToSelect('*')
    ->addAttributeToFilter('is_active', 1) //only active categories
    ->addAttributeToFilter('include_in_menu', 0) //only categories not included in menu
    ->addAttributeToFilter('parent_id', 10)//get only subcategories of the category with id 10
    ->addAttributeToSort('position')//sort by position
;

foreach ($collection as $category) {
    //do something with $category
}
