[Plugin: Magic Fields 2] Dropdown List

use get_label https://wiki.magicfields.org/doku.php?id=front-end_functions_v20#get_label

i mean in back-end.
when i add dropdown type and fill it items it creates metabox with select tag and option attribute title=value

<select>
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>

but if i vant something like this?:

<select>
  <option value="my_value_volvo">Volvo</option>
  <option value="saab_12345">Saab</option>
  <option value="mer-ced-es">Mercedes</option>
  <option value="audi-audi-audi">Audi</option>
</select>

maybe add items with new syntax –
Volvo=my_value_volvo
Saab=saab_12345
etc….
