In Ultimate FAQ, you can create categories, which you can then assign your FAQs to. This is helpful for grouping similar FAQs together (e.g. product information, shipping information, returns information, etc.).
If you go to the Categories page in the plugin admin, you’ll see an overview of all your existing categories.
You can sort them by clicking on one of the headings in the table. You can also search for a category.
To edit a category, click its title.
On the left side, you can create a new category.
While you are able to create sub-categories (as it does make use of WordPress’s taxonomy system), there will be no benefit to doing so. When displaying the FAQs on your site, there is an option to separate the FAQs by category, but this does not extend to sub-categories. On the front end, sub-categories are treated and displayed the same as categories.
You can, however, still use sub-categories for your own organizational purposes, keeping in mind that there is no way to display nested categories on your site.
