This project provides an administrative interface for adding custom tabs to content entities. These tabs can display various types of content, such as view modes, forms, or actions, and include granular access control options.
Provides an admin UI for building tabs on content entities of any type.
Each tab is a config entity, which defines the tab path component, page title, and so on, as well as the plugin to use to provide the content. Tab content plugins can show view modes, form modes, action forms, or indeed any kind of content.
Each tab has its own access permission, with permissions granular to bundles on the target entity and entity owners (for entity types that support owners).
This is the spiritual successor of Drupal 7's Entity Operations.
