YJSG v2 is completely modular and gives you a chance to extend each part of it as well as Joomla article options. If you look in site_root/templates/eximium/custom/yjsgarticle/ folder you will find file name yjsg_article.xml.
We have placed one custom parameter inside as an example. You can use this file to add any additional options that you might need for your articles.
To see this article parameter in action copy the html override from plugins/system/yjsg/includes/html/com_content/article/default.php
to templates/eximium/html/com_content/article/ folder.
Please note that if you are using a template that was released prior to Yjsg v2, you would need to copy the file located in plugins/system/yjsg/legacy/html/com_content/article/ folder.
Open the newly copied file and after the first php closing ?> add this snippet.
Now go to your article view page and you will se the parameter output.
