I have added a dropdown tag filter to my blog, though for some reason, it is not displaying the tags of the posts that are published in the dropdown. Strangely i have used this method for other blogs before without any issues.

The dropdown displays visually as it should, though published tags do not show from the dropdown list.

I have used the following code within my blog listing template:

\<div class=“tag-dropdown”\>

{% set my\_topics = blog\_topics(‘default’, 250) %}

\<select id=“blog-topics”\>

\<option\>Filter by topic\</option\>

{% for item in my\_topics %}

\<option value=“{{ blog\_topic\_url(group.id, item.slug) }}”\>{{ item }}\</option\>

{% endfor %}

\</select\>

\</div\>

JS

\<script\>  
$(function(){  
$(‘#blog-topics’).on(‘change’, function(){  
var link = $(this).val();  
if(link != “Filter by topic”){  
window.location.href = link;  
}  
});  
});  
\</script\>

Any suggestions would be hugely appreciated.

The blog\_topics function has been deprecated, you should use blog\_tags instead. Also blog\_tag\_url instead of blog\_topic\_url.

{% set my\_topics = blog\_tags(‘default’, 250) %}

{{ blog\_tag\_url(group.id, item.slug) }}

Piers, you are na absolute hero. Thank you so much for your feedback on my post.  
I was not aware of the 'blog\_topics being deprecated. I last used this method around 6 or so months ago, so it’s great to finally see a solution.

I appreciate your time. Thank you once again.
