Layout Builder

What This Plugin Adds

Layout Builder is an Available, Schema-owning Capell package in the Capell Foundation product group. It ships as capell-app/layout-builder and extends these surfaces: admin, frontend, console.

Layout Builder adds a visual page composition workflow with layout areas, widgets, reusable widgets, presets, and reversible layout edits.

Editors can add, reorder, resize, and edit page widgets in admin. Visitors receive the saved layout graph as ordinary public output without authoring markers.

Status details:

• Status: Available
• Tier: free
• Bundle: foundation
• Composer package: capell-app/layout-builder
• Namespace: Capell\LayoutBuilder
• Theme key: not applicable

Why It Matters

For developers: Registries and typed Actions provide stable extension points for widget definitions, layout widgets, presets, and public render data.

For teams: Choose Layout Builder when page composition changes; use Content Sections for reusable published sections or Structured Content Library for typed records such as testimonials and FAQs. Both can feed a Layout Builder composition. If a site only needs a few fixed templates, its existing Laravel templates may be enough.

Screens And Workflow

Screenshot contract: docs/screenshots.json.

Content Composition

The Page and its blueprint remain Core inputs. Layout Builder owns the areas, widget keys, widget definitions, and widget assets that BuildPublicLayoutGraphAction turns into a public layout graph; Frontend owns the final public render contract.

Canonical Mermaid source

What changes when you edit an article, its layout, or its theme? In this illustrative example, A day on the coast uses main for an article content widget and sidebar for a related-reading widget; these are example choices, not seeded defaults.

• Content edit: revise the article title or body in its blueprint-defined content; the example keeps its main and sidebar placements.
• Layout edit: move or reorder widget placements in the selected layout; this changes composition and may affect other pages sharing that layout.
• Theme change: change templates, typography, spacing and area presentation. Check the theme's available areas and widget support; switching themes does not guarantee an identical composition.

Source: BuildPublicLayoutGraphAction maps layout containers and ordered widgets into public data; LayoutLoader resolves widgets and their assets. Page, Blueprint, Translation, Layout and Theme remain Core models; Widget and WidgetAsset belong to optional Layout Builder.

Cache tags

Data Model

• Required tables: layouts, widgets, widget_assets, widget_widgets, layout_presets, layout_bulk_change_runs, layout_bulk_change_results, layout_preset_usages, layout_preset_sync_runs, layout_preset_sync_results, public_widget_snapshots.
• Models: Layout, LayoutBulkChangeResult, LayoutBulkChangeRun, LayoutPreset, LayoutPresetSyncResult, LayoutPresetSyncRun, LayoutPresetUsage, PublicWidgetSnapshot, Widget, WidgetAsset, WidgetWidget.
• Core record references in migrations: sites via site_id, languages via language_id, layouts via layout_id, widgets via widget_id, themes via theme_id.
• Migration files: 2026_05_10_190841_02_create_widgets_table.php, 2026_05_10_190841_03_create_widget_assets_table.php, 2026_05_10_190841_04_create_widget_widgets_table.php, 2026_05_10_190841_05_add_container_widgets_to_layouts_table.php, 2026_05_10_190841_06_create_layout_presets_table.php, 2026_06_07_000001_create_layout_bulk_change_tables.php, 2026_07_09_000001_create_public_widget_snapshots_table.php, 2026_07_10_000001_add_linked_preset_fields_to_layout_presets_table.php, 2026_07_10_000002_create_layout_preset_usages_table.php, 2026_07_10_000003_create_layout_preset_sync_runs_table.php, 2026_08_28_000003_change_widget_visibility_to_datetime.php, 2026_09_01_000001_add_shadowed_by_workspace_id_to_widgets_table.php.
• Migration impact: run host migrations through the package install flow before opening package surfaces.
• Deletion/retention behaviour: migrations declare cascade-on-delete relationships and null-on-delete relationships; retention is scheduled through capell:widget-snapshots:prune (daily; declared in the manifest) and capell:layout-builder:prune-bulk-change-runs (daily; declared in the manifest).

Install Impact

• Required packages: capell-app/core, capell-app/admin, capell-app/block-library, capell-app/frontend.
• Admin navigation: declares admin-resource: LayoutBuilderAdminRegistrar; each Filament page or resource controls its own navigation visibility.
• Admin/editor extensions: configurator: LayoutBuilderAdminRegistrar, schema-extender: LayoutBuilderAdminRegistrar.
• Permissions: ViewAny:Layout, View:Layout, Create:Layout, EditContent:Layout, EditLayout:Layout, Update:Layout, Delete:Layout, DeleteAny:Layout, Restore:Layout, ForceDelete:Layout, Replicate:Layout, Reorder:Layout, BulkMutate:Layout; access also governed by package policies: LayoutPresetPolicy.
• Public routes: registers LayoutBuilderRoutesContribution.
• Database changes: package migrations are declared.
• Config: config/capell-layout-builder.php.
• Settings: no package settings declared.
• Queues or schedules: scheduled commands capell:layout-builder:prune-bulk-change-runs (daily; manifest declared), capell:widget-snapshots:prune (daily; manifest declared); queue jobs ApplyLayoutBulkChangeRunJob, SyncLinkedLayoutPresetJob.
• Cache tags: layout-builder.
• Commands: capell:layout-builder-install, capell:layout-builder-widget-visual-regression, capell:layout-builder:prune-bulk-change-runs, capell:layouts:bulk-change, capell:widget-snapshots:prune.

Common Pitfalls

• Keep required Capell packages on compatible v4 releases: capell-app/core, capell-app/admin, capell-app/block-library, capell-app/frontend.
• Run migrations before opening package resources or public routes.
• Review package configuration before production-like verification: config/capell-layout-builder.php.
• Keep the host Laravel scheduler running so package-registered schedules can execute: capell:layout-builder:prune-bulk-change-runs (daily; manifest declared), capell:widget-snapshots:prune (daily; manifest declared).
• Keep public Blade and cached HTML free of authoring markers, model IDs, permissions, signed editor URLs, and lazy database queries.
• Custom write integrations must preserve invalidation for layout-builder cache tags.

Troubleshooting

| Symptom | Likely cause | Check | Fix | | --- | --- | --- | --- | | Package surface is missing after install | Provider or manifest is not loaded | Confirm capell.json, package composer.json, and provider registration | Reinstall the package, refresh Composer autoload, and clear host caches | | Admin screen or command fails on missing table | Package migrations have not run | Check the tables listed in Data Model | Run host migrations and rerun the focused package test | | Background work does not run | Queue worker or declared schedule is not active | Check the jobs and scheduled commands listed in Technical Shape | Start the queue worker or host scheduler, then run the focused command or package test | | Public output leaks unexpected state | Render data, cache variation, or authoring boundary has regressed | Check public Blade, cache tags, and public-output safety tests | Move data loading out of Blade and rerun the package public-output tests |

Quick Start

1. Install the package: composer require capell-app/layout-builder.
2. Run the package setup: php artisan capell:layout-builder-install.
3. Open the package admin surface at /admin/layout-builder/widgets and confirm Layout Builder is available.
