I understand. In general though, is there a way to display custom post types via the Blog Post element?
Unfortunately our new website that we are working on is only seen locally at the moment. I can though, show you our current live site that is using a different theme builder and has achieved the desired result. Please visit: http://www.varsityfs.com/additional-resources/. This page is a regular page I created and I added the feature image as the image at the top of the page. I then, through our current theme builder, used a similar tool as the Blog Post builder to combine multiple Custom Post Types on one page. Each section on this page (Case Studies, White Papers, Brochures) are individual custom post types. When creating the section, similar to how you would with the Enfold Blog Post element, I could also choose the Custom Post Type I wanted displayed. Not just a category or tag.
Below is a video screen show of what I see through the enfold builder: http://screencast.com/t/4McUYtqxcxOr. Note there is no option to select my custom post types: Case Studies, White Papers, etc.).
As far as I can tell, all I can do is view an archive page but I can’t edit the archive page. As a reminder, we are looking for a non-php solultion as I’m doing content and don’t have access to the php.
