I have looked at other questions on this matter, but would like to be clear on what is the 'correct' approach to this. Example: https://stackoverflow.com/questions/13715665/joomla-override-category-blog-output-multiple-times
I have already created an override for the category blog layout, this effects any menu items etc that point towards the Category Blog layout in my template.
//templates/template_name/html/com_content/category/blog.php / blog_children.php etc etc.
What I would now like to do is create a completely separate blog layout. Specifically this is for a Shop category in the main menu. I would like to style this completely differently to how my main category blog override is already created. What is the 'correct' method to complete this? Are there any walkthroughs/explanations on what needs to be created where to get me started.
