How can i separately import projects contents only from other Prebuilt websites?

Hi bestshop24h,

Thanks for reaching to us.

You can create a dev site and import any template there, then with the help of the import functionality of Elementor you can export its template, more detail is here: https://elementor.com/help/template-library/

Devsite – also called a Staging platform where you can test issues, enable/disable features/plugins thus such changes will affect the main site. The below article will help you to create it:
