Meta Box

You are correct and that fixed my problem. I assumed that, even if the field was empty, the prefix label that was indicated would display. It's obvious now to me that if the field is empty nothing shows.

Thanks for your help with this. Much appreciated.

Thanks for the help with this. I've followed the directions and can successfully add some custom fields to a single page or all pages of a website and access them through Elementor.

I now want to take this a slight step further and can't figure out how to connect a field group to an Elementor header template. That is, I want one or more dynamic fields in a header made in Elementor to be connected to a Meta Box field group.

I surmise that in order to do this I would employ 'advanced location rules' in the settings section of a field group. However, I've tested any of the 19 drop-down options that appear to logically and potentially connect to an Elementor template and have had no success. Perhaps this isn't possible, but it seems to me that an Elementor template is just another post type to WP and there has to be a way! Can you help me do this?
