Greenshift can be used not only directly in Gutenberg but also in other page builders like Bricks, Elementor, Oxygen, Divi.
You can’t edit Greenshift blocks directly in these editors, but you can create reusable templates and copy shortcodes to page builders.
This way can be used not only for shortcode rendering but also for Ajax loading. Imagine that you have a very heavy part of the page, but you want to improve the speed of the site. You can put this area in the reusable template and load it only on Ajax by clicking, view, hovering on special elements, etc
To create blocks as shortcodes, use Reusable templates – Add new. Then, you can copy its shortcode and use it on other pages or page builders. Check also video how to use Ajax loading
