概要

Generates Angular Material code and guidance for Angular projects using `@angular/material` with the Material 3 (M3) theming system. Covers installation, Sass-based theming via `mat.theme()` and the prebuilt palettes, density and typography customisation, component usage across all categories (form controls, buttons, overlays, layout, data display, navigation), `@angular/cdk` primitives (Overlay, Portal, Drag-Drop, Virtual Scroll, A11y), ReactiveForms / Signal Forms integration via `mat-form-field`, accessibility, and the M2 → M3 migration. Use when the user mentions Angular Material, `@angular/material`, `mat-*` components, M3 / Material 3, design tokens, OR when the Angular project's `package.json` contains `@angular/material`. Pairs with `angular-developer` for Angular fundamentals.

Angular Material Developer Guidelines

Pairs with angular-developer , that skill provides Angular fundamentals (signals, DI, routing, forms, SSR, accessibility). This skill focuses on Angular Material specifics. Install both for the best experience.

Compatibility

Tracks: @angular/material@22.1.1 (Angular v22), paired with @angular/cdk@22.1.1 (Material peers an exact cdk version, keep the two pinned together). The v21-aligned line remains at 21.2.x for legacy projects.
Animations peer dropped (v21.2+): Material no longer declares an @angular/animations peer dependency and animates via native CSS. ng add @angular/material on 21.2+/22 does not wire provideAnimationsAsync() and does not require @angular/animations, do not add either to a fresh Material 22 app. (Earlier v21.x and all v18-20 apps still need the provider; see setup.md.)
Works for: Material v19 → v22 projects (M3 theming system landed in v19; older majors used M2 with the now-legacy mat.define-light-theme / mat.define-dark-theme API).
Angular: v19 or newer required. v22 requires Node 22 or 26 and TypeScript 6. The skill assumes standalone components, control flow (@if / @for), and signal-based APIs.
Sass: required for theming. The build pipeline must support .scss (Angular CLI does by default). Standalone CSS-only theming is not supported by Material's theming engine.
Not supported: Material v18 and below (M2-only with mat.define-*-theme() API), Angular v18 or below (NgModule patterns + older animations API).

v22 breaking changes (from v21)

The v21 → v22 jump has real API drift, not just an Angular version bump. Watch for:

Combobox: legacy combobox and autocomplete promoted / removed. SimpleCombobox promoted to Combobox with all simpleCombobox* symbols renamed to combobox*.
List: MatListOption.checkboxPosition removed, use togglePosition instead. MatListOptionCheckboxPosition renamed to MatListOptionTogglePosition.
CDK: injector parameter is now required on ConfigurableFocusTrap and FocusTrap constructors. ConfigurableFocusTrapFactory.create boolean parameter replaced with a config object. DropListRef.drop event parameter is now required. ContextMenuTracker renamed to MenuTracker. Removed: CDK_DESCRIBEDBY_HOST_ATTRIBUTE, CDK_DESCRIBEDBY_ID_PREFIX, MESSAGES_CONTAINER_ID.
Multiple components: input/model rename from values to value across Combobox, Listbox, Tree, Menu, Toolbar, Select. Constructors with rest arguments removed (affects code that extends Material or CDK components).
Dialog / Overlay: ArrowViewState and ArrowViewStateTransition types removed.

Most of these have automatic ng update migrations. When in doubt, run ng update @angular/material and let the schematic do the work before hand-editing.

v22 new features worth knowing

Signal Forms stable (was experimental in v21). Angular's signal-based form API is now safe to use in production. mat-form-field composes with both ReactiveFormsModule and Signal Forms.
Angular Aria stable (was preview). New accessibility primitives ship in the framework, which reduces the need to reach for CDK's a11y module for some patterns.
Button progress indicator support inside <button> component.
Portal directives support on ComponentPortal.
Separate tab animation durations (per-tab enter/exit timing).

Check the project's Material version before answering. Material's M3 theming engine was introduced in v19 (mat.theme() mixin replacing mat.define-light-theme and mat.define-dark-theme). Code generated against M3 will silently break on M2 projects. package.json is the source of truth.
Detect the theming generation in styles.scss:
- If you see @include mat.theme((...)) → M3 (v19+, default). Use mat.theme(), Material's prebuilt palettes, and CSS variable overrides.
- If you see mat.define-light-theme(...) or mat.define-dark-theme(...) plus @include mat.all-component-themes($theme) → M2 (legacy). Recommend migrating, see migration.md.
- The two systems compile and behave very differently. See theming.md.
Components are standalone since v15. Always import the standalone class (e.g. MatButton from '@angular/material/button'), not the legacy MatButtonModule. The modules still re-export everything for backwards compatibility but should not be added to new code.
After generating Material code, run ng build. The most common AI mistakes are: (a) using v17-era mat.define-light-theme syntax in a v19+ project (compiles but silently emits no CSS vars); (b) forgetting provideAnimationsAsync(), which makes ripples, menu open/close, and dialog backdrop animations no-op; (c) missing @angular/cdk peer dep, Material imports cascade through it; (d) using MatTable without a MatSort / MatPaginator wiring up, the column header sort UI appears but does nothing.

Material architecture: components, CDK, theming

Angular Material ships three layers:

Components (@angular/material/*) , the styled mat-* components themselves: MatButton, MatFormField, MatTable, MatDialog, etc. Each lives at its own import path.
CDK (@angular/cdk/*) , unstyled primitives Material composes on top of: Overlay, Portal, A11y (FocusTrap, LiveAnnouncer, ListKeyManager), DragDrop, VirtualScroll, Stepper. Always installed as a peer dep alongside Material. Useful on its own when you need a primitive but don't want Material's styling. See cdk.md.
Theming engine (@angular/material/_index.scss) , the Sass mixins (mat.theme(), mat.theme-overrides()) that emit CSS variables consumed by every component. Sass is required, no CSS-only theming path.

Default to importing from @angular/material/<component> (e.g. MatButton from '@angular/material/button'). Reach for @angular/cdk/<primitive> only when you need the headless primitive or are building a custom-styled component composing Material's behaviour.

Installation and theming

Setup: ng add @angular/material (handles the install + writes a default theme; on v18-v21.1 it also wires provideAnimationsAsync(), on 21.2+/22 it does not, Material animates via native CSS), or manual install. Read setup.md
Theming (M3): mat.theme() mixin, prebuilt palettes (mat.$violet-palette, mat.$azure-palette, etc.), density and typography knobs, light dark color-scheme, per-component overrides via mat.<component>-overrides(). Read theming.md
M2 → M3 migration: the v19 ng-update schematic + manual fix patterns. Read migration.md

Components

Angular Material documents 40+ components grouped by category. Each category file below covers the components, their key inputs, common patterns, and gotchas.

Form Controls: Autocomplete, Checkbox, Datepicker, FormField, Input, Radio, Select, Slider, SlideToggle. Read form-controls.md
Buttons & Indicators: Button, ButtonToggle, Badge, Chip, Icon, ProgressBar, ProgressSpinner, Ripple. Read buttons-indicators.md
Layout: Card, Divider, ExpansionPanel, GridList, List, Stepper, Tabs, Tree. Read layout.md
Navigation: Menu, Sidenav, Toolbar. Read navigation.md
Popups & Modals: BottomSheet, Dialog, Snackbar, Tooltip. Read overlays.md
Data Table: Table, Paginator, Sort, MatTableDataSource. Read data-table.md

CDK primitives

CDK: Overlay, Portal, A11y (FocusTrap, FocusMonitor, LiveAnnouncer, ListKeyManager), Drag-Drop, VirtualScroll, Stepper, ScrollDispatcher, Layout (Breakpoints). Read cdk.md

Forms integration

Forms: Wiring Material components to ReactiveForms (the canonical path) and Signal Forms (Angular v22+) via mat-form-field, MatInput / MatSelect / MatDatepicker, ErrorStateMatcher patterns, <mat-error> display, and ControlValueAccessor for custom controls. Read forms.md

Accessibility

Accessibility: Material's WCAG 2.1 AA targets, FocusMonitor for keyboard-vs-mouse focus styling, LiveAnnouncer for transient announcements, RTL support, the things Material gives you free and the things you still need to do. Read accessibility.md

Preserve the core workflow, adapt paths to this repo, and keep the rule scoped to tasks where it is relevant. Skill purpose: Generates Angular Material code and guidance for Angular projects using `@angular/material` with the Material 3 (M3) theming system. Covers installation, Sass-based theming via `mat.theme()` and the prebuilt palettes, density and typography customisation, component usage across all categories (form controls, buttons, overlays, layout, data display, navigation), `@angular/cdk` primitives (Overlay, Portal, Drag-Drop, Virtual Scroll, A11y), ReactiveForms / Signal Forms integration via `mat-form-field`, accessibility, and the M2 → M3 migration. Use when the user mentions Angular Material, `@angular/material`, `mat-*` components, M3 / Material 3, design tokens, OR when the Angular project's `package.json` contains `@angular/material`.
