At first, find ‘FAQs’ menu from the left sidebar of your wp admin panel, then add as many faqs as you want.
After that, create a New Page using ‘FAQ’ template and publish the page. See the screenshot below:
Your FAQs page is ready. You can visit the page you just published and you will see all the faqs you added are here. Now, to have the bottom 3 menus like the live preview faq page, you need to visit ‘FAQ template page’ settings from your ‘Theme-Options’.
