How can I write html in while inside php using fetch_array data?

I tried many things but i just cant make the value of option an id from database and i cant write the option as date and title from database im doing this so far, any help would be appreciated.

<select name="agenda "size="10">
            <?php
            global $connection;
            $result = mysql_query("SELECT * FROM agenda where date > now() order by date", $connection);
            $i = 0;
            while ($row = mysql_fetch_array($result) && $i < 20)
                {
                $id = $row['id_agenda'];
                $date = $row['date'];
                $title = $row['title'];
                //here i would like to make an option with 
                //value = id_agenda and write the date_agenda and title_agenda
                //something like this
                //<option value="$row[$id]">$date $title</option>
                $i++;
                }
            ?>
            <option value="Google">meeting 2</option>
        </select>
