You won't normally see drop-downs or other selection type boxes in our Profile Mapping area. The reason is that Facebook's data will most likely not match up with the options you give your users. For gender, I believe Facebook uses "Male" and "Female". So, those would have to be the exact settings you'd offer your users. We're working on a better way to handle gender specifically, since it's (usually) an either or option.
As for country, if you're interested in testing a change that may work for countries, there's a minor code change you can make below. If you edit the /plugins/jfbcprofiles/jomsocial/jomsocial.php file, around line 527, you'll see the following line:
$query = 'SELECT * FROM #__community_fields WHERE type="text" OR type="textarea" OR type="date" OR type="birthdate" ORDER BY ordering';
Update that to the following (adding the --OR type="country"--)
$query = 'SELECT * FROM #__community_fields WHERE type="text" OR type="textarea" OR type="date" OR type="birthdate" OR type="country" ORDER BY ordering';
That will add the Country field to the Field Map area of JFBConnect Profiles. Then, set the correct Country field from Facebook to import into it. It's likely that the countries from Facebook will 'align' with what JomSocial allows, but there may be some countries that don't work perfectly. However, if you expect the majority of your users to come from the 'major' countries, it will hopefully work as expected. Please, please, please test and let us know how well the field gets imported and if it seems correct with the options available in JomSocial!
Some things to look for are is that Facebook (I believe) will return "United States". I don't know what JomSocial uses, but if it's U.S.A or United States of America, that would look like 2 different countries that your users may be from.
You can add "radio" or "select" to the query above and that will also show your radio or selection drop-downs (for things like Gender), but again, be aware that what imports from Facebook may not be the same as what you offer as options on your site.
Hope that helps, but if you have any questions, just let us know!
Thanks,
Alex
