I’d like to use a different template for my 404 error pages. I’ve been playing with Elementor and they now let you customize the 404 pages. However, I don’t see a way to choose their “Elementor Canvas” Template for 404 pages like I can from the Page Attributes section of a regular wordpress page. What is the recommended way to do that?
from within the Elementor Editor you can select the layout from the Cog icon and select Canvas. Alternatively i actually use a GP PageHeader (which can include Elementor shortcode content) assigned to the 404 template. This way i can maintain the rest of my theme content.
