# Declarative actions

Learn how the Workspace declarative actions function with CRM Workspace.

Declarative actions add custom functionality to your CRM Workspace forms, fields, lists, and related lists without writing custom scripts or learning APIs. Declarative actions include: form and list actions, related list actions, and field decorators.
