An FAQ page serves two valuable purposes. It is great for visitors who have questions and want fast access to answers. It is also good for SEO, as there are plenty of relevant keywords and phrases.
You can categorize your questions, as maybe Buyers, Sellers, or any other ways you want. Just change the button text and put your FAQs in the right category. The question is in bold above the answer.
Any question and answer you enter with a button highlighted will then display only under that button or the ALL button.
