Adds four field types for selecting parts of your content model rather than content itself:

Section — entry sections
Entry Type — entry types (Craft 5 decoupled these from sections)
Product Type — Craft Commerce product types
Tag Group — tag groups

Instead of relating to specific entries, an author picks what kind of content a block should pull in, and you drive a query from that. Ideal for page builders and "latest N from X" blocks.

Settings

Multiple Select — allow one or several選 options
View Mode — radio buttons/checkboxes, or a dropdown/multi-select for long lists
Select All, plus explicit allow and exclude lists
Select By Text In Handle — auto-allow anything whose handle matches
Template Value — return plain IDs, or objects exposing all(), ids(), handles(), names()

Full GraphQL support for queries and mutations.
