How to add select option in drupal while creating content type

Whenever you create any content type in drupal ( version 6 and above) and you required a filed of type select list, then you can provide the allowed values of the select option in two ways

CASE 1 :

option 1
option 2
option 3

CASE 2 :

1|option 1
2|option 2
3|option 3

Each new option has to be entered on a new line
So enternally the select list generated would be as follows
In case 1 :

<select>
<option value=”option 1″>option 1</option>
<option value=”option 2″>option 2</option>
<option value=”option 3″>option 3</option>
</select>

In case 2 :

<select>
<option value=”1″>option 1</option>
<option value=”2″>option 2</option>
<option value=”3″>option 3</option>
</select>
