Hi friends. I was successfully added needed field to database with my module.
 

        //If column 'attribute_group.attribute_description' does not exist, create it
        Db::getInstance(_PS_USE_SQL_SLAVE_)->query('SHOW COLUMNS FROM `'._DB_PREFIX_.'attribute_group` LIKE "attribute_description"');
        if (Db::getInstance()->NumRows() == 0) {
            Db::getInstance()->execute('ALTER TABLE `'._DB_PREFIX_.'attribute_group` ADD `attribute_description` TEXT NOT NULL DEFAULT  ""');
        }

Can you help me to show my field with 'displayAttributeGroupForm' hook at my module?
Or maybe I need to use override AdminAttributesGroupsController.php way?

Thank you. Yegor.

Looks like I can print needed field with this method but I am not sure yet that it is the best way

 

    public function hookDisplayAttributeGroupForm($params)
    {        
        //code
    }

Or best way it is override controller?

Was created needed module with override admin controller and attribute class.
