I'm trying to create a form field in edituser.php that can use items from a defined list in xoopslists.php, but can also accept text entry. Within the context of the XoopsFormSelect class, is this possible?

For example, I've added a country field to the user table and can fill it with a dropdown list in edituser.php using the XoopsFormSelectCountry class. However, I would like to allow the user to alternatively input their own text for the "country" field, if they don't see the selection they want in the dropdown list.

I've not seen this used in any of the other dropdowns used in Xoops. Thanks in advance for any help.
