Почему аккордеон не расширяется или разрушается при нажатии?

Question

Я использовал это, чтобы развернуть и свернуть div, нажав на знак +, но это не так.Он остается неподвижным и не расширяется и не разрушается.Я пытался добавить и удалить все нежелательные сценарии, но все равно он не работает.Также консоль имеет ошибку:

Uncaught TypeError: $ (...). SlideReveal не является функцией

Вы добавляете дополнительный атрибут data-parent="#accordion" в строку <div id="collapseOne" class="collapse" aria-labelledby="headingOne">.Я только что удалил этот атрибут в приведенном ниже фрагменте кода.Я надеюсь, что это поможет вам.Спасибо

Answer 2
