Hello There,
Thank you for the clarifications! Cornerstone elements are all shortcodes. You just can’t use it in normal WP editor because you will need to have the exact shortcode before it will work. If you do it your way, you will have 50% error in doing so because most of the time, you can not accurately place the shortcodes the correct way. We do not have the complete list of shortcodes and its options available for reference. Most of the v2 elements are complex shortcodes. The contents of these shortcodes were placed somewhere in the post meta which is why, even if you create a page in Cornerstone and get the shortcodes and use it in the normal WP editor like what you did added this:
[cs_element_content_area _id="13"]
or this:
[cs_element_content_area_off_canvas _id="30"]
will definitely not work. Of course it will be difficult to use when using shortcodes and html with the WP editor. That is why we have Cornerstone. V2 elements are here to help users focus on creating/building the page design without knowing anything to code. You cannot use V2 elements shortcodes outside of Cornerstone. It will not display anything. All the V2 elements must only be used exclusively for Cornerstone and in Pro theme header and footer builders.
Hope this helps.
