Hi I have just updated to version 2.2.2 on Joomla 1.0.15 and have had a bit of trouble with my custom fields.
I had a field with a drop down list which is there but the drop down list has disappeared from the frontend.
The rest of the custom fields seem to be there and I have them enabled for individual and group registration but for some reason they don\'t show up on group registrations.
Yes, as of 2.2.2 you need to insert a size for the dropdown field. The size is in PIXELS. Try 200 as a starting point, check it, then modify as needed.
