Normally, in a joomla article, I disable the editor and enter the code and it works perfectly. But in "T4 page builder" it doesn't work. I am disappointed in "T4 Page Builder", it is very limited, it serves to create a very simple home page. In "T4 Page Builder" you can't add code to a button, you can't show a Joomla article, it's literally to make a landing page and nothing else.
