What's a Compound Field? Imagine a cake recipe. It consists of ingredients to bake this cake. Every single ingredient consists of multiple atomic values: amount, metric (tsp, tbsp, cup, gram, ml), a description, calories, etc. In a recipe, however, an ingredient is a single, cohesive field that consists of combined data values.
This session will give an overview of the Field API in Drupal 8, and show how to create custom compound fields (fields with multiple data values). These fields can initially be used in content types, and then further extended to be used in Form API forms. This session will also cover the basics of atomic design principles.
Alternatives to custom module development such as the Paragraphs module are frequently preferred. However in certain cases, a custom compound module may be in order. One aspect of this session will discuss when to use core or contrib options vs. creating a custom solution. It will also cover some other contrib options for handling complex fields.
