Hi, thank's for this greate code.i have quation how can'i filtring categories collection by this cutom attribute.

Thanks!

@rafiqeladli like this:

/* @var $collection Mage_Catalog_Model_Resource_Category_Collection */
$collection = Mage::getResourceModel('catalog/category_collection');
$collection->addAttributeToFilter(
    'my_custom_attribute' // <!-- Change this to your actual category attribute
    '1' // Supplying "0" would filter by categories set to "no" instead"
);
