Advanced Webforms
summary
Covers how Webform for Drupal 8 stores forms as config entities and submissions as content entities, exposes APIs, plugins, and handlers to build custom elements, post submissions, and export data, and shows concrete patterns: copy-and-extend existing render-element plugins, use YAML or PHP render arrays, test with a dedicated test module (the project ships 225 test forms), validate Ajax modal confirmations, assert access control (password element returns 403), and extend the remote-post handler noting remote post lacks authentication so custom auth is needed.
