I created a WordPress theme and now i want to save all content images, menus, post, pages. If i’ll install my new theme on a new server i want to have a method for import demo content. I exported theme content with WordPress from Tools -> Export but it exports only pages and posts. I need to export menus and images too. If you recommend me a plugin, please explain me how my theme will ask the new user for require plugins. Any resource will be useful. Thanks!
