Get the field of the parent pages if it's empty or not exists. It goes all up till the site.

Manually

Download and copy the plugin into your plugin folder: /site/plugins/

With Composer

composer require plain/kirby-inherit

Let's say you want to get a hero image. The editor can set it on each page. But he don't have an image for every page. Use this code to look if the parent page has a image set:

    $page->hero_image()->inherit()

It goes all way up. At the end it will take the imgae from the main site.

You can also use it for another page:

    $page->hero_image()->inherit( page('another_site') )
