У меня есть контроллер, который возвращает модели с параметрами сохраненного поиска, которые select2 должен загрузить в частичное представление.
Когда некоторые параметры имеют id = 0, что означает, что select2 был пуст при сохранении, отображаются в форме в соответствующем раскрывающемся списке как первое значение вместо пустого (0).
