I have found it useful in a custom post type to use render_callback if you choose to have more than one template. For example, I have different templates for the single post view and a grid view of all of my posts. The render_callback function can pick which template to use.
Thanks for your answer. I realize that I did not put one part of my questions correctly…
Can I wrap just some of the html elements in a div so that I would have a div as a container for some of the fields. Hope this makes sense
thanks again.
