%labels = ('eenie'=>'your first choice',
'meenie'=>'your second choice',
'minie'=>'your third choice');
print $query->popup_menu('menu_name',
['eenie','meenie','minie'],
'meenie',\%labels);

popup_menu() creates a menu.
1. The required first argument is the menu's name
(-name).
2. The required second argument (-values) is an array
reference containing the list of menu items in the
menu. You can pass the method an anonymous array, as
shown in the example, or a reference to a named array,
such as "\@foo".
3. The optional third parameter (-default) is the name of
the default menu choice. If not specified, the first
item will be the default. The values of the previous
choice will be maintained across queries.
4. The optional fourth parameter (-labels) is provided
for people who want to use different values for the
user-visible label inside the popup menu nd the value
returned to your script. It's a pointer to an asso-
ciative array relating menu values to user-visible
labels. If you leave this parameter blank, the menu
values will be displayed by default. (You can also
leave a label undefined if you want to).
