Lightning App Builder — Advanced Configuration
This skill activates when a practitioner needs to go beyond basic drag-and-drop page layout in Lightning App Builder (LAB). It covers component visibility filter logic, custom page templates, Dynamic Forms and Dynamic Actions at depth, LWC targetConfig constraints, and page performance optimization. Use it alongside dynamic-forms-and-actions when the task involves the full LAB canvas rather than just field-level visibility basics.
Before Starting
Gather this context before working on anything in this domain:
- Confirm the org edition: Dynamic Forms and Dynamic Actions require Enterprise Edition or higher. Group and Professional editions cannot use these features.
- Identify the target object: Dynamic Forms supports most custom objects and a growing subset of standard objects (check the current Salesforce release notes — the supported list expands each release). Objects not yet supported will not show the "Upgrade Now" option in LAB.
- Check whether existing page-layout actions are present on the record page: enabling Dynamic Actions while page-layout actions are still assigned causes duplicate action buttons unless you remove the page-layout actions from assignments first.
Core Concepts
Component Visibility Filters
Every component on a Lightning record page, app page, or home page can have up to 10 visibility conditions. Conditions use AND or OR logic (not a mix of both in one component rule — you pick one operator for the whole set). Filter criteria types include field value (evaluated client-side at page load and on change), record type, profile, custom permission, device form factor (Desktop, Phone, Tablet), and user attribute. Summer '24 extended per-condition visibility to individual tabs inside the Tabs standard component, so each tab can be shown or hidden independently without requiring separate page variants.
Important security note: visibility filters are cosmetic. A component hidden by a filter is not rendered in the DOM for the current user under most circumstances, but FLS (Field-Level Security) must independently enforce data access. Do not use visibility filters as a security gate.
Dynamic Forms
Dynamic Forms moves individual field components and field section components onto the LAB canvas and assigns per-component visibility rules. This replaces the monolithic field section derived from the page layout. When Dynamic Forms is enabled for a record page, the page layout's fields are no longer injected automatically — they must be explicitly placed as components. Migrating via the "Upgrade Now" wizard converts existing layout sections to Dynamic Form components, but any fields not in the layout at migration time must be added manually.
Not all standard objects support Dynamic Forms. For unsupported objects, the workaround is to use multiple page layouts assigned per profile/record type, or to create formula fields that expose calculated values in supported ways.
Dynamic Actions
Dynamic Actions moves the action bar to the LAB canvas and adds per-action filter conditions using the same visibility criteria available for components. Once you enable Dynamic Actions for a record page, the action bar is no longer controlled by the page layout's action section. If the page layout still has actions and is assigned to users, those actions will show in addition to the Dynamic Actions bar — causing duplicates. Remove the page-layout action assignments before or immediately after enabling.
Custom App Page Templates
A custom app page template is an Aura component that implements lightning:template. The component's .cmp file defines flexipage:region nodes with name, defaultWidth, and optional maxComponents attributes. These regions become drop zones in the LAB canvas. LWC cannot directly implement the lightning:template interface, so custom templates must be Aura. However, LWC components can be placed inside template regions as content components. LWC components targeting lightning__RecordPage in their .js-meta.xml targetConfigs cannot expose recordId in the <targetConfig> design resource — recordId is injected automatically by the framework; exposing it in design causes a metadata validation error.
Common Patterns
Complex Visibility Using Formula Fields
When to use: When your visibility condition requires logic that cannot be expressed in a single filter (e.g., "show only when Stage is Closed Won AND Amount > 10000 AND account billing country is US"). LAB visibility filters cannot do cross-field arithmetic or multi-level expressions.
How it works: Create a formula checkbox field (e.g., Show_Contract_Section__c) whose formula encodes the full logic. Then use that single checkbox field as the one visibility filter condition on the component. This keeps the LAB filter simple (one condition: Show_Contract_Section__c = True) and offloads complexity to the formula engine.
Why not the alternative: Attempting to chain 10 conditions in LAB for complex cross-field logic becomes brittle and hard to maintain. Formula fields are versioned, testable, and reusable across multiple page components.
Mobile-Optimized Page Variant
When to use: Record pages that perform well on desktop become slow on mobile due to component count and heavy LWC components loading simultaneously.
How it works: Create a separate page variant for Phone form factor using the "New Page" > "Form Factor" option in LAB. Limit visible components to 8 or fewer per region (Salesforce-documented mobile performance guideline). Use visibility filters with Device = Phone to hide non-essential components on the shared variant instead of fully duplicating the page.
Why not the alternative: Assigning the same desktop page to mobile users without optimization causes cascade loading delays because all components — even those below the fold — begin loading simultaneously.
Decision Guidance
| Situation | Recommended Approach | Reason |
|---|
| Object supports Dynamic Forms, need per-field visibility | Enable Dynamic Forms, use field component visibility filters | Native, declarative, no code |
| Object does NOT support Dynamic Forms | Formula fields + component-level visibility or multiple page layouts | Dynamic Forms unavailable; formula field visibility is next best |
| Need to show/hide entire action bar buttons per record context | Enable Dynamic Actions, remove page-layout action bar assignment | Avoids duplicates; gives declarative per-action control |
| Need visibility logic beyond 10 conditions or cross-field math | Formula checkbox field as single filter proxy | LAB filter limit is 10 per component |
| Building reusable page template for multiple app types | Custom Aura template component with flexipage:region | Only Aura can implement lightning:template |
| Performance issue on mobile | Create Phone form-factor variant, cap to 8 components per region | Official mobile component count guideline |
| Per-tab visibility in Tabs component (Summer '24+) | Use per-tab visibility settings in Tabs component properties | Available since Summer '24; no need for multiple page variants |
Recommended Workflow
- Confirm org edition (Enterprise+), target object Dynamic Forms eligibility, and whether existing page-layout actions are assigned (Dynamic Actions duplicate risk).
- Open Lightning App Builder for the target record page. Review the current component structure and identify which components need visibility rules, which need Dynamic Forms, and whether Dynamic Actions is required.
- For each component requiring visibility: add filter conditions (up to 10, AND or OR), using formula fields where the required logic exceeds what inline filters can express.
- If enabling Dynamic Forms: use the "Upgrade Now" wizard, verify all layout fields migrated correctly, then assign field-level visibility rules to each field component.
- If enabling Dynamic Actions: confirm page-layout action assignments are removed to prevent duplicates, then add per-action filter conditions in LAB.
- If building a custom template: scaffold an Aura component implementing
lightning:template, define flexipage:region nodes, deploy to org, then reference the template in LAB New App/Page.
- Validate using the Preview (Desktop and Phone form factors), check the Review Checklist below, and activate the page.

Salesforce-Specific Gotchas
- Visibility filters are cosmetic, not security — A component hidden by a visibility filter is not a security control. FLS and object permissions are the only enforced data access gates. Users with direct API access or SOQL tools will still see field data regardless of visibility filters on the page.
- Dynamic Actions + page-layout actions = duplicates — Enabling Dynamic Actions does not automatically remove the page layout's action section from the page. If that layout is still assigned to users, both the Dynamic Actions bar and the page-layout actions render simultaneously, duplicating buttons.
- Dynamic Forms Upgrade Now can silently miss fields — The migration wizard only migrates fields that are currently on the page layout at the time of migration. Fields added to the layout after the migration, or fields not in the layout at migration time, must be manually added to the canvas as individual field components.
