I added page content (designed with Page Builder) to a Below header theme extension (added as page with shortcode through text widget).
Below header widget is rendered but with default style, not responsive.
In Page Builder I draw 1 row with 2 columns, but in widget it is rendered one below another as a simple UL/LI list.
That same page (design with rows w/2 columns) is correctly rendered when opened directly, as a page. But it’s rendering in widget is problematic.
I also tried adding that page to Below header extension through Widget Builder plugin, but the same.
