Hello,
Thank you very much for choosing our theme and for contacting us.
WoodMart is compatible with WCFM.
If you use WP bakery page builder, you need to reset WordPress or reinstall all and install Elementor in the net installation. It is not possible to switch from WP bakery page builder to Elementor.
All the demos you see are available in Elemntor. In addition, there is the template library: https://xtemos.com/docs/woodmart/templates-library/
Best Regards
