Display Gutenberg Blocks in Elementor
You can display PostX Gutenberg blocks into Elementor by using the Elementor and Save Template Addons.
Use Gutenberg Blocks in Elementor
Save Template and Elementor addons work together to create a custom design using the PostX Gutenburg blocks and use them into Elementor via shortcode. So, first of all, you need to create a custom template to generate the shortcode. Then you can use the shortcode while editing any page with Elementor.
Elementor and Gutenberg Integration
Elementor and Gutenberg both are different types of page builders. But, with help of the Elementor and Save Template addons of PostX, you can create a page using the features of both of the builders.
