This article applies to all Content Types in your WordPress Dashboard.

To delete a piece of content:

1.) Navigate to its ‘edit’ page;

2.) In the ‘Publish’ box you will see a red link titled ‘Move To Trash’:

While in the trash, this content is still available to website administrators, but will not be visible on the live website. At this point, the content can still be recovered from the trash by navigating to the list-view of the content type and selecting ‘Trash’ from the horizontal list of items (other items listed might be ‘All,’ ‘Published,’ and ‘Drafts’). Clearing the trash will delete the content forever.

It is important to note that every Content Type, except for the Media Library, has a Trash. When an item is deleted from the Media Library, it is permanently deleted immediately.
