includes\modules\classic\attributes.php
在大约786行代码
case ($products_options->RecordCount() == 1):
的下面找到
$options_menu[] = zen_draw_radio_field(‘id[‘ . $products_options_names->fields[‘products_options_id‘] . ‘]‘, $products_options_value_id, ‘selected‘, ‘id="‘ . ‘attrib-‘ . $products_options_names->fields[‘products_options_id‘] . ‘-‘ . $products_options_value_id . ‘"‘) . ‘<label class="attribsRadioButton" for="‘ . ‘attrib-‘ . $products_options_names->fields[‘products_options_id‘] . ‘-‘ . $products_options_value_id . ‘">‘ . $products_options_details . ‘</label>‘ . "\n";
替换为
$options_menu[] = zen_draw_pull_down_menu(‘id[‘ . $products_options_names->fields[‘products_options_id‘] . ‘]‘, $products_options_array, $selected_attribute, ‘id="‘ . ‘attrib-‘ . $products_options_names->fields[‘products_options_id‘] . ‘"‘) . "\n";
即可。
