It's possible, using Ghost's tag system, to show Cove comments only on certain posts (or pages).
We will use Ghost's internal tags for this example. An internal tag starts with a # symbol. These tags are hidden from your blog's theme and are only used in the background to organise posts.
Step 1: Create the tag
Add a tag like #cove to the posts (or pages) that you want to show Cove comments on.
Step 2: Tweak the Cove install code
We now want to only load Cove on posts and pages with the #cove tag.
To do this, we have to make a small change to the Cove install code: just wrap a {{#has}} block around the standard Cove code.
{{#has tag="#cove"}}
{{#if @labs.members}}
<h2><span id="cove-count"></span> Comments</h2>
<div id="cove"></div>
...
{{/if}}
{{/has}}And that's all 👍
The {{#has}} helper is very powerful. Make sure you to read through the full documentation to explore some other useful ways to use it in your theme.
