Моя проблема в том, что я использую Angular 6, Bootstrap v4 и jQuery для карусели с несколькими предметами. Если у меня есть данные, подобные [1,2,3,4,5,6], то на карусели это должно показать [1,2,3]. После нажатия следующей цифры нужно показать [4,5,6].
До этой части я достиг, я столкнулся с проблемами. Только первая активная карта перемещается, и есть также отставание, и предыдущая и следующая кнопки не видны. Пожалуйста, проверьте файл Stackblitz, который вы поймете.
Вот моя работа в Штабблице
