How can I create another Blog posts page, but showing posts from a specific category (and its subcategories) not all by default. I ahve two different types of content and they dont go well when displayed together.
You can use Posts Grid element provided by MotoPress Page Builder The plugin is integrated into the theme. It allows to filter posts (and custom post types) by categories, tags and custom taxonomies. Also you can define the quantity of posts and columns to display, show/hide meta, etc.
