If you need to get elements/pages from different demos there are 2 ways:
– XStore studio allows import sections from different demos, when you are using Elementor plugin. Just edit page using Elementor > click here – https://prnt.sc/udpfle and import the desired block.
– If you are using WPBakery Page Builder, do not enable the Elementor, but watch this video – https://youtu.be/wkIKN2IyEZI
If you are using WPBakery, the Studio can’t be used.
