You may want to hide a Page or Post in WordPress for a variety of reasons: it’s in draft mode and you aren’t done composing it, it’s for an event that hasn’t been announced, or it’s an expansion of your site that you aren’t ready for. No problem!
Put a Page or Post in Draft mode – when you’re editing your Page or Post, look in the right column “Publish” section. If its already published, you’ll see “Status: Published [Edit]“. Click “Edit”, select Draft from the drop-down menu, click OK, and click the blue Update Post button. The Page or Post should no longer be visible on the site.
