Question

WordPress

Please tell me how to create a separate page for displaying posts of a certain category, if on the main page, in the index.php file, I display posts and I need to create, for example, news-post.php, and display certain posts in this file and so that I can menu go to this page

Answer 1

1) create a page and remember the id of this page
2) create a template. For example, page-{id}.php
3) In the template, display the WP_Query loop and specify the category to be displayed or the id of the posts to be displayed, etc.
