Dynamic Forms, Dynamic Actions and visibility rules

How component, tab, field and action visibility filters work on Lightning pages, what changes when a record page moves to Dynamic Forms (field sections, create and edit windows, mobile, cross-object fields), and how Dynamic Actions put filtered actions on desktop and mobile.

Official exam objective
Given a scenario, determine the appropriate solution to enhance or extend the UI/UX with applications (App Manager, Lightning App Builder, Dynamic Forms, standard Lightning page components, Console, and Lightning page analyze button).

What the exam expects

  • Build visibility filters for components, tabs, fields and actions, and know which contexts each page type offers.
  • Work around the visibility filter limits (five spans, single values, supported field types).
  • Migrate a record page to Dynamic Forms and predict its effect on create, edit and clone, hidden fields and mobile users.
  • Add cross-object fields and page-only read-only or required settings without changing field-level security.
  • Enable Dynamic Actions on a record page and on mobile for standard and custom objects.

Key terms:

  • Visibility filter: a condition that hides a component until its filter logic is met.
  • Dynamic Forms: Field and Field Section components that replace the page layout's Record Detail block.
  • Record Detail - Mobile: the component that shows page layout fields to mobile users on a Dynamic Forms page.
  • Dynamic Actions: actions assigned and filtered in the Lightning App Builder instead of the page layout.
