function select_with_style_field_widget_form in Select with Style 7

Implements hook_field_widget_form().

Called by core when a user selects either the 'select_optgroups' or 'select_tree' or widgets. Also when the user edits a node. A hook_form_alter() implementation isn't going to cut it, as the select_tree or select_optgroups field won't be on the form without this function!
