CSS3 data attributes stripped from customized output

Hi,

The reason this get’s stripped out is because I have wp_kses_post being run on the HTML so as to ensure that it is compatible with the post HTML that WordPress allows.

You can strip out this function from:
https://plugins.trac.www.ads-software.com/browser/contextual-related-posts/trunk/admin/admin.php#L75

Thanks. Rather than stripping out core code, I used the following workaround:

1. added <ul class="replace"> to ‘HTML to display before the list of posts:’
2. Added to following php to my page template:

   $related = do_shortcode('[crp limit="6" heading="1" cache="1"]');
   $related = str_replace('replace"','kopa-featured-news-carousel" data-pagination-id="#single_related_posts_pager" data-scroll-items="3"',$related);
   echo $related;

Hope this is useful to others.

This is definitely a good workaround, since you won’t need to edit any of the plugin files!
