How to create your own template on the post output page of the created Custom Post Type plugin?

Question

WordPress

I decided to create a Custom Post Type plugin, the posts are displayed, but the page apparently loads the native WP template from the Posts page. How to remove the unnecessary sidebar and header, i.e. to make your own template for the post output page of your choice.

Answer 1

Hello!
Explore the template hierarchy...
In short:
taxonomy-TAX_NAME.php (for taxonomy)
single-CPT.php (for single post)
Copy templates archive || category.php rename to taxonomy.php (as above)
Copy single.php and rename to single-CPT.php
And there you can already edit as you like
