They have created the layout Portfolio, for giving us the option to load a Article Layout, with the following
<field name="article_layout" type="componentlayout"
This loads the default option: Use Global; what I would like is to know how to modify the code to load the default purity_iii/html/com_content/article/portfolio.php file is Article layout for the portfolio.
or if I can provide any documentation xml options I have for com_content
From already thank you very much.
