You can turn the display of all tags or individual tags off/on. This will also affect the tag listing/results screens.
This feature can be useful in a number of ways, for example if you are prepping a new tag to go live and want to attach it to all your relevant FAQs/Articles but don't want it to display just yet you can simply leave it switched off until you are ready.
You can turn Tags off globally in Settings --> FAQs --> General (under the "Listings" heading)
Individual tags and their associated listings/results can be turned off via FAQs --> Tags then the three-dot menu to the right of the tag in question
