Any regular Sitecore users knows there are many ways to publish an item. However it’s not always obvious how to “unpublish” an item. Its actually quite straight forward.
1. Navigate to the item you want to unpublish using the Content Editor. From the Publish ribbon select the Change button:
In change dialog, make the item unpublishable by deselecting the Publishable checkbox:
The content editor will display are warning informing you what’s about to happen.
The final step to actually publish the item and it will disappear from the front-end but remain in the master database. This may sound strange, but as the item is already published we need to publish again to remove it from the web database.
