To remove content, select the Delete link for the page, comment, attachment, or blog post. For a page or blog post, the Delete link is on the Tools menu.
If you do not see the delete link, contact your project manager or team lead about your permissions, or send a message to Application Support.
For more information, refer to the following page:

You can delete several pages together, if necessary. For example, consider the following procedure if you no longer need a set of draft pages for a software release.
To check for potential broken links before deleting several pages:
- Move those pages into a separate page family. For example, you could create a "Pages to Be Deleted" page for this purpose.
- Request a deletion of the whole "Pages to Be Deleted" page tree. Confluence notifies you of potential broken links in that page tree.
If you proceed with the deletion, you can restore the parent page of the deleted page family (the "Pages to Be Deleted" page in the above example) from the Trash for reuse. The other pages remain in the Trash.
