Random displaying of post

All in all yes, there’s ways to do this. It won’t be with Custom Post Type UI alone, as we don’t have any functionality around content display.

If you’re wanting to avoid coding in general, then something like https://www.ads-software.com/plugins/random-post-on-refresh/ looks like it’s exactly what you need.

Otherwise, you’re going to want to make use of WP_Query in some way if you’re not wanting to use someone else’s plugin.

Ok, thanks a lot. I thought, there is a way to do that without WP_Query. Just to use some loop through my post type and choose one of them and display it. I’m affraid, that WP Query will be affected by repeaters from Oxygen.

Noted. WP_Query would be getting used at some point along that entire line of execution because it needs to fetch the posts at some point. I believe it even may be used if providing a list of IDs.

I think that plugin is worth a try just to see how things go with it. Perhaps if necessary avoid using it within a part of Oxygen that isn’t repeater based.
