A production-ready set of checkbox widgets covering multiple visual styles—Smooth, Android/Material, Minimal square, Neumorphic, Round Ripple, Image-state, and Tri-state. Each variant ships with crisp micro-interactions (morphing checkmark, ripple, glow), robust state handling, and first-class accessibility. Fully themeable and purpose-built for high-density forms and filter panels.

Functionality

• Seven presets + custom builder: Smooth, Material, Minimal, Neumorphic, Round Ripple, Image-state (custom icons/bitmaps), Tri-state.

• Tri-state support: checked / unchecked / indeterminate with parent–child aggregation (“Select all” with partial state).

• Animated transitions: checkmark path morph, scale/fade, ripple/halo, optional haptics; duration/easing tokens.

• State model: hover, focus, pressed, selected, disabled, error/warning/success; tooltips and assistive messages.

• Form bindings: initialValue, validation, error text, onChanged/onSubmitted, controller APIs; group helpers (select all/none/invert).

• Accessibility: ARIA roles (checkbox), screen-reader labels, tab/space/enter navigation, focus rings; RTL & Reduce Motion ready.

• Theming & sizing: radius, stroke width, icon set, fill/outline/ghost variants, elevation/shadow, density (S/M/L), color tokens for light/dark.

• Performance: layer caching and GPU-friendly drawing for butter-smooth 60fps in long lists.

Use cases

• Settings and preference forms (privacy, notifications, feature flags)

• E-commerce faceted filters (brand, size, availability)

• Admin dashboards with bulk actions and partial select banners

• Surveys/quizzes (multi-select choices) and onboarding consents

• Checklists/To-do and QA workflows with success/error feedback
