В приведенном ниже коде есть 2 раскрывающихся списка текстовых и двух полей. Это обновление, когда я выбираю код курса из тематической таблицы курса, и он публикует значения в раскрывающемся списке тематического кода и обновляется до mysql, но когда я выбираю код курса из раскрывающегося списка, перекрывает таблицу. Моя идея состоит в том, чтобы заполнить значения в текстовом коде и обновить в mysql.опубликовать значение в раскрывающемся списке и обновить до mysql

я наклоняю возможность popoulate значение в теме кода –
