Custom Post Formats enable you to customize your asides, images, and other types of posts. Doing so is a great way to bring character and definition to an otherwise amorphous collection of regular posts. Then, as your custom-formatted posts grow in number, your site will feature uniquely styled archives for each of your Custom Post Formats.
To help your visitors find and enjoy your Post Format Archives, here is a widget that displays a menu with links to each of them. It’s a great way to open up your site and showcase your custom content.
