say if from your database you can read two column values areaid and areafullname.
just insert and menu list as regular html, replace the value part with <?php echo($valuesfromdatabase); ?>. and use the while loop to get the values from the database.
<select name="areaid">
<?php
$sqlselectarea= "SELECT * FROM AREA";
$selectarearesult=ibase_query($dbconn, $sqlselectarea);
while ($arearow = ibase_fetch_object ($selectarearesult))
{
$areaid=$arearow->AREAID;
$areafullname=$arearow->AREAFULLNAME;
?>
<option value="<?php echo ($areaid); ?>"><?php echo ($areafullname); ?></option>
<?php
}
?>
</select>
