Bootstrap Dropdown закрывает все меню только на мобильном телефоне

Question

Вечер!У меня проблема с меню Bootstrap: только на мобильном устройстве (как только на устройствах Apple), когда вы нажимаете на раскрывающееся меню Bootstrap, оно закрывает все меню.Затем, когда вы снова нажимаете кнопку гамбургера, раскрывающийся список раскрывается.Этого не происходит в Chrome, Firefox или Safari, когда я уменьшаю размер окна ...
