Как создать трехбуквенный аккордеон и список-группу с помощью Bootstrap

Question

Я пытаюсь создать интерфейс, подобный этому здесь:

Вкратце - вот чего я пытаюсь достичь: Есть три раздела - все связаны друг с другом. Крайний левый раздел предназначен для глав, в которых есть подглавы, складывающиеся по щелчку. Когда выбран SubChapter, в средней части открывается список вопросов. У каждого вопроса есть область ответа, а эта находится в крайнем правом разделе, который появляется при выборе вопроса.

Я не мог заставить аккордеон Bootstrap работать, поэтому я пошел с list-groups и получил это: Пример в Codepen

Поскольку каждая глава в ряд, очевидно, когда я добавляю главу 2, она отталкивается списком вопросов. Такое ощущение, что выбранная раскладка неверна ... Буду признателен за любые намеки на это. Спасибо!

Текущий код ниже:
