Готов заплатить за доработку...
Необходимо чтоб получилось так https://prnt.sc/knrqo2
1. При нажатии на радиокнопку становятся активными элементы на против нее, а в противоположном блоке выбрать ничего нельзя и на всех элементах снимается active, пока не переключить радиокнопку.
2. Первый вариант выбирает диапозон, второй конкретные дни.
3. Должно работать на основании имеющегося скрипта.
Сейчас у меня так:
