Unfortunately, it doesn't support custom fields at this moment, I've forwarded to our GK team for further consideration on this feature.

Add custom fields to News Show Pro
Hi Saguaros, thank you for responding so quickly, now I have another question, is it possible to add custom fields to override the category articles module?
vgutierrez2012 Perhaps this topic can help you
Hi Saguaros, I have a group, with 7 custom fields, each one with its id, entering the article, from the editor I try to add them as these tutorials explain:
https://www.joomla-monster.com/documentation/joomla-tutorials/custom-fields-in-joomla-3-7
https://www.joomlashack.com/blog/tutorials/custom-fields/
The only thing that needs to be added to the article is "{field 1}" but when updating it does not load field 1, will it be a problem with the Joomla version?
vgutierrez2012 Could you share the URL of page and screenshot highlighting the part you want to add that custom field?
I will take a look.

Hi Saguaros, in this article I need to add the custom field from Google map, but I can't do it:

Here is the image showing how to load a "custom field" inside an article but neither in Joomla 4 nor in Joomla 5 it works, it's very strange:

vgutierrez2012 It seems to be Joomla issue as I tried to embed the same field to article with Joomla fresh installation + Cassiopeia template but it doesn't work.
Hi Saguaros, I changed the template on the website, using Cassiopeia and the custom fields load without problem

vgutierrez2012 The issue came from the setup for the article content, normally an article has intro text + full text separated by the readmore button. The above article doesn't have readmore button so template considers it as intro text so the field doesn't show there.
I just updated this file: /templates/ja_purity_iv/html/com_content/article/default.php
This line of code: <?php echo HTMLHelper::_('content.prepare', $this->item->text); ?>
and the field is showing now, kindly check.
Thanks Saguaros, everything works perfectly, in files "layout-1" and "layout-2" I changed on line 227.
The code above that didn't show the custom fields:
<?php echo HTMLHelper::('content.prepare', $this->item->fulltext); ?>
I changed it to:
<?php echo HTMLHelper::('content.prepare', $this->item->text); ?>
Now, the custom fields are displayed within the article, without problem.
vgutierrez2012 Glad to hear that
