Is there a way to show only some tags in ruby?

In ruby theme we can see tags on side of the page…
I want to show some tags only and not others …
Is there a way to do it??

Yes, you can show a limited number of tags at anyplace in your ghost themes. Just control tags using limit="all".

{{#get "posts" limit="5"}}
{{/get}}

I have used here number 5 for showing tags. You can change with your number.

Thanks

Where am I supposed to put this?

You can put this where you want to show your posts.

{{#get "posts" limit="5"}}
  {{#if posts}}
    {{#foreach posts}}
    <article class="{{post_class}}">
      <h2 class="post-title"><a href="{{url}}">{{title}}</a></h2>
      <p>{{excerpt words="26"}} <a class="read-more" href="{{url}}">&raquo;</a></p>
      <p class="post-footer">
        Posted by {{primary_author}} {{tags prefix=" on "}} at <time class="post-date" datetime="{{date format='YYYY-MM-DD'}}">{{date format="DD MMMM YYYY"}}</time>
      </p>
    </article>
    {{/foreach}}
  {{/if}}
{{/get}}
