Tell us what you are trying to do?
I'm refreshing sections of the site using elementor, and the same short code used to display 'brothers' can't work.
In Step 2 of the documentation below, will it work if the Child Content Template is created using elementor?
The key for this to work is using a content template called with the id="$parent" attribute to set the required context (the parent page template in the linked article).
That template must be a Toolset template.
I wouldn't expect it to matter if you designed the main (child) template with Elementor, and inserted the parent template as described with the id attribute, in a text module.
I don't know for sure that it will work. This would be one of those cases where, if it does, it does, and if it doesn't it doesn't, I'm afraid.
Placing the shortcode using the elementor short code widget produces the earlier error i had.
Placing the shortcode using the text editor widget solves the issue.
