Как настроить раскрывающийся список в соответствии с размером экрана, чтобы раскрывающийся список не выходил за пределы экрана

Question

[введите описание ссылки здесь] [1] Я работаю над проектом в этом проекте, мне нужно выпадающее меню, которое не выходит за пределы экрана в адаптивном режиме. в режиме рабочего стола раскрывающийся список отображается правильно, но в мобильном режиме раскрывающийся список выходит за пределы экрана, поэтому раскрывающийся список отображается неправильно.

вот ссылка js fiddle для этого кода
