The other day I was working on a site where the client wanted a page where the posts of just one category would show. I wanted a pretty url (not with /category/ in front of it) so I was getting ready to create a custom page template for it when I discovered this super easy way to create a category page with the Genesis Framework.
Simply use your Custom Fields area. This area can be found under your text editor when you are editing your page,right under the Theme SEO Settings. If you don’t see it, check your Screen Options at the top right of your screen.
Simply add query_args in the first section and then your category ID # in the second as shown above where my category ID was 18. If you are not sure of your category ID#, simply go to Posts > Categories and then hover over the category that you want to use. The ID# will appear in the url at the bottom of the screen when you hover over the name.
Then, just make sure your template is set to the default Blog and you are all set!
