Can I group my store-wide FAQs into sections like Shipping and Returns?

Yes. Use FAQ categories.

1. Go to Product FAQs and open the Categories tab. Enter a Category name (for example "Shipping & Delivery"), add an optional description and click Add. Click Active or Inactive next to a category to switch it on or off.
2. On the Global FAQs tab, choose a category from the drop-down when you add an FAQ. For existing FAQs, click Edit, pick the category and click Save.
3. On the Settings tab under Global FAQ page (/faq), tick Show the category filter and set FAQs per page, then click Save settings.

If you delete a category, its FAQs are kept and become Uncategorised.
