In the previous post, I described why we chose Layout Builder and how Layout Builder IPE restored the frontend editing workflow we had used with Panels IPE.

With the editing workflow in place, we still had to rebuild the elements that editors placed on their pages.

The Drupal 7 site used custom ctools content type plugins for maps, charts, figures, lists and tables. Editors placed and configured these plugins, while the plugins retrieved the information and rendered the result. I will call both these ctools plugins and the block plugins that replaced them page elements.
