Related Files

Navigate to your post/page and input the ID’s of the file(s) into a custom field with the name:
Related Files ID

If adding multiple files separate with commas.

Files will automatically be appended to the post/page. The positioning of this will depend on the template used, but typically these are inserted towards the top of the post/page, wrapped with the standard WordPress ‘alignright’ CSS class, which will float this content to the right.
