Question in HTML form "Drop Down Menu"

[like_php]

I make database for sending mail to mail groups , which contain two tables the first one for the main table , contain all group information "groups_inf " , and the second one for groups categories "group_type" .

I make page for inserting data to the "group_inf" table , by using form and make drop down menu for group categories , and sending value to "group_type" field in "group_inf" table .

and in mailing page , I put the the drop down menu too for "group_type" .
the action for this form page "sending.php" .

I want make if condition in sending.php page , if group type = Yahoo , sending for yahoo group mailing list .

else , sending for mn groups .

and so on .

how can use if condition in drop down menu.

echo '<option value="something"';
($group == 'Yahoo' && $selected == 'Yahoo') ? ' selected' : '';
echo '>Something</option>';
