Category Order and Taxonomy Terms Order is a powerful plugin to re-order categories and all custom taxonomies terms using a drag and drop capability. The best thing about this plugin, we don’t need to change theme code just to re-order categories and taxonomies, the plugin will do it for us. Just drag and drop category or taxonomy terms, voila! this plugin sort this out without any programming to theme files.
If multiple taxonomies are created for a custom post type, a menu will allow to chose the one need sorted. If child categories (terms) are defined, those can be order too using the same interface
