Let me admit upfront that I am not a developer. I can usually get by if I can cut & paste. And it may be that the product is too much for me.
I've created Custom Fields using MB Builder. The Custom Fields are set under Posts.
If I use Elemenator Theme Builder, with an archive template, I can get the custom fields to display. That is good.
If I use Elemenator Theme Builder, I can build a template using dynamic tags. With the Preview Dynamic Content set for 1 of the Custom Posts, I can see the data. But when I change the Preview Dynamic Content to All, I get nothing.
This is, as an example, what I am trying to accomplish. We have a number of employees. The data for each employee is used in multiple templates on multiple pages.
I love what I have been able to do with your plugin. I simply frustrated by what I am not able to do.
