Hello! If you want your template to completely override the content area of your custom post type, you can use the “Layouts” content type instead of “Templates” to apply your L&L to those single posts.
If you don’t want to override the entire content you have a few options with varying degrees of complexity:
If you’re using a page builder themer like FSE, Beaver Themer or Elementor Pro, you can add your template to your layout.
If you’re comfortable with PHP, you can register new theme positions for your layouts (in addition to the default “Content” location). This method is outlined in this forum post.
If the template for the post type is a PHP file (single-{cpt_slug}.php) in your child theme you’re comfortable modifying (or if you’re able to create an override by adding the file to your child theme) you can use the tangible_template function to render your template directly in your PHP file.
I hope one of these approaches works for you! If you want help registering a new theme position, I’d be happy to help if you can let me know which theme you’re using and where you’d like your template to render.
