Everything is fine in other browsers, but in IE8 and IE9,
some fields fall OUTSIDE of the div.ninja-forms-all-fields-wrap.
So in the HTML structure, it looks like a tag is closed before wrapping the other fields.
My form currently uses a list of radio buttons. The div.ninja-forms-all-fields-wrap wraps every field until the end of that radio buttons list.
The remaining fields are out of the structure.
Any ideas ?
