Drupal site builders often encounter recurring use cases, such as grouping fields together or providing hierarchical lists of options. There are common approaches to these use cases, based on core functionality such as Taxonomy or on contributed solutions such as Paragraphs - But there are drawbacks to these approaches.

In this session we explore a couple of common use cases, how one might go about solving the problem with core and contrib modules, and what kind of limitations may surface. From there, we look at how custom field types may help solve these problems and what kind of logic should drive the decision making process - examples included.
