Since the theme uses posts for multiple things, in order for the "Next Post" and "Previous Post" buttons to display correctly, I opted to browse through the primary_tag.

{{#prev_post in="primary_tag"}} /* Previous post with the same tag*/

{{#next_post in="primary_tag"}} /* Next post with the same tag*/

In simple terms, this means all your announcement posts should have the same tag, which is not empty. If left empty tagged, Ghost will browse through all of your posts, including the collapsibles and selectors. You can name the tag whatever you like, or even use different names if you don't want any previous/next post buttons.

• collapsible
• selector Those tags are used to display the select and collapse page template correctly. For more information, view Templates.
