Hello, how to remove the comma in tags with {{putPostTags(item.post_lists.id)}} ?

Thanks.

My item html :

<div class="metamorphoz_article_grid_style_six_box">
  <div class="metamorphoz_image_box">
    <div class="metamorphoz_article_img" style="background-image: url({{item.post_lists.image}}); height: {{metamorphoz_img_height}}px;"></div>
    <a href="{{item.post_lists.link}}"><div class="metamorphoz_overlay"></div></a>
  </div>

  <div class="metamorphoz_box_content">
    <div class="metamorphoz_title"><a href="{{item.post_lists.link}}"><h3>{{item.post_lists.title|raw}}</h3></a></div>
    <div class="metamorphoz_extrait">{{item.post_lists.intro|raw}}</div>
    <div class="etiquette">{{putPostTags(item.post_lists.id)}}</div>
  </div>

</div>

Thanks, it's good :)
