Открытия контент Bootstrap аккордеон под родительский DIV

Question

Я пытаюсь открыть каждый div под их родителями div, но мой code открывает каждый div под первым изображением, где никто не может видеть. Я чувствую, что использую position неправильно?

.collapse { 
    position: relative; 
    bottom: 0; 
}
