GAP stands for Great Ajax Post plugin and it does what it says. This plugin can be used to filter and sort all your posts by smart filters like: post types, author, category and even Advanced Custom Fields (ACF).
The GAP filters also includes a slider filter to filter metakeys that includes numbers. This also works on ACF fields.
You can choose between 2 styles to display your posts: image style or text style!
