When using page templates with Shopify's Online Store 2.0, we recommend that you create a separate page template for each of your pages.
Page templates hold the content and settings of sections you've customized in the Theme editor. If you create a second FAQ page and use the same template, all the same content will be shown from the first FAQ page. For that reason, creating a new page template is needed to show different content.

Configure the page settings and sections.
