I have a Wordpress site that I used the 'Posts' menu to create product pages as the site works as a catalog with no online purchasing. I am now trying to set up a blog in the same install. Is it possible to duplicate the 'Posts' menu option and page functions to create a new admin menu for 'Blog'. My goal is so that the blog and products function separately so you won't have access to a product post when in the blog section.
Yes, you need to create a new post type.
