If you to use Elementor, then you can. But, it isn’t compatible with the core block editor, so no Blocks including GenerateBlocks will work with it. And you would need Elementor Pro if you want to add Lists of Posts to the page ( i think its only a Pro widget – could be wrong ).
OK, so that means I can not work with GenerateBlocks. Then I will see what Elementor offers in these terms. And later maybe I can upgrade to Elementor Pro.
