What Can You Do With The Accordion Module?
The accordion was created to make the creation of Frequently Asked Questions pages easier. You can use the accordion feature to expose the questions in your FAQ, but keep the answers hidden until the accordion exposes the question. The answers are exposed by users when they click on the question.
Depending on the number of questions and the size of the answers, the FAQ can be organized as a single page, or as a separate post for each question and answer.
In the latter case posts can be placed in a single FAQ category or across multiple FAQ subcategories.
