If I firstly create the Setcions and after edit this page with Elementor – my Sections design breake (not support full width Sections design and properties of background color in Sections are lost too).
Please give me advice how to combine Sections and Elementor in 1 page. Thank you )
If you really want to do this the workaround is to use Elementor Templates, which is a pro add-on only. Any Elementor section (or page) can be saved as template. Then go to Dashboard > Elementor > Template Library and within each template will have a shortcode that you can paste into a GP Section.
