This code may helps you

$options = array();
                        foreach ($areas as $row)
                        {
                             $options[$row->id]=$row->descricao;

                        }
                        echo form_dropdown('areas', $options, $record->id);

And,i hopes you already loaded form_validation library files in your controller

$this->load->library('form_validation');
