How to have a Tag Column?

Support
2

You’d have to override the handlebars template for the topic list items as well as the topic list header (see Developer’s guide to Discourse Themes )

Adding this to admin > customize > themes > edit HTML/CSS > desktop > </head> gives you something to start with. You’ll need to add custom CSS to style as you see fit.

<script type="text/x-handlebars" data-template-name="topic-list-header.raw">
    {{#if bulkSelectEnabled}}
      <th class="bulk-select">
        {{#if canBulkSelect}}
          {{raw "flat-button" class="bulk-select" icon="list" title="topics.bulk.toggle"}}
        {{/if}}
      </th>
    {{/if}}
    {{raw "topic-list-header-column" order='default' name=listTitle bulkSelectEnabled=bulkSelectEnabled showBulkToggle=toggleInTitle canBulkSelect=canBulkSelect}}
    {{#if showPosters}}
      {{raw "topic-list-header-column" order='posters'}}
    {{/if}}
    {{raw "topic-list-header-column" sortable=sortable number='true' order='posts' name='replies'}}
    {{#if showLikes}}
      {{raw "topic-list-header-column" sortable=sortable number='true' order='likes' name='likes'}}
    {{/if}}
      <th>Tags</th>
    {{#if showOpLikes}}
      {{raw "topic-list-header-column" sortable=sortable number='true' order='op_likes' name='likes'}}
    {{/if}}
    {{raw "topic-list-header-column" sortable=sortable number='true' order='views' name='views'}}
    {{raw "topic-list-header-column" sortable=sortable number='true' order='activity' name='activity'}}
</script>


<script type="text/x-handlebars" data-template-name="list/topic-list-item.raw">
    {{#if bulkSelectEnabled}}
  <td class="bulk-select">
    <input type="checkbox" class="bulk-select">
  </td>
{{/if}}

{{!--
  The `~` syntax strip spaces between the elements, making it produce
  `<a class=topic-post-badges>Some text</a><span class=topic-post-badges>`,
  with no space between them.
  This causes the topic-post-badge to be considered the same word as "text"
  at the end of the link, preventing it from line wrapping onto its own line.
