Assign the tags/labels you want to pull dynamically via Custom Data in CleanSlate CMS.

dynamic-tags.html

---
layout: default
custom_data_attributes:
  - tags_to_pull
---
<!--
  Step 1: ☝️ Add the `tags_to_pull` custom data attribute to the
  page template you want to output the feed on.
-->


<h2>Configuring tags/labels to pull dynamically via Custom Page Data</h2>
<r:set_var name="blog_context_tags" value={$tags_to_pull}" />
<!--
  Step 2: ☝️ Since we're using `get_page_id` below, we have to assign the tags
  in *this* page's custom data into the context of the blog index page.
-->

<r:get_page id="1234"> <!-- Step 3: 👈 Change the ID to your blog index's page ID -->
  <r:articles:each tags="{$blog_context_tags}" tags_op="any">
    <ul>
      <li><a href="<r:article:url />"><r:article:name /></a></li>
    </ul>
  </r:articles:each>
</r:get_page>
