Select2 is a searchable, modular UI framework designed to enhance standard HTML select elements. It transforms basic form controls into interactive, accessible dropdown interfaces that support multi-selection, tagging, and real-time filtering. By providing a robust set of tools for managing complex data inputs, it enables developers to create more responsive and user-friendly selection components. The project is distinguished by its adapter-based architecture, which allows for deep customization of rendering, data processing, and selection logic. Developers can extend core functionality throu

jsoneditor is a web-based JSON editor component designed for viewing, editing, and formatting structured data. It provides a user interface for managing JSON through multiple rendering modes, including tree, form, and code views. The project is distinguished by its ability to process and visualize exceptionally large datasets, utilizing virtualized memory management to handle JSON files up to 500 MiB without crashing the browser. It also includes a specialized syntax repair tool to convert malformed text into valid JSON and a data transformer for filtering, sorting, and reshaping documents vi

Opentui is a terminal user interface framework for building interactive command line applications. It provides a component-based system featuring a flexbox layout engine, a virtual node component tree, and a low-level 2D cell array renderer. The project is distinguished by a sophisticated keyboard binding engine that maps complex multi-stroke sequences and chords to named commands using prioritized, reactive layers. It also implements a plugin architecture that allows external modules to inject custom UI components into designated layout slots and extend input logic at runtime. Its capabilit

This project is a JavaScript spreadsheet component and web-based data table that provides an interactive grid for managing tabular data. It functions as a cross-framework UI component compatible with React, Vue, and jQuery, and can also be embedded as a standalone web component. The grid is specifically designed for XLSX interoperability, allowing users to import and export XLSX files while preserving formulas and styles. It distinguishes itself through real-time collaboration for simultaneous multi-user editing and a flexible system for creating custom cell editors and specialized column typ

Zag ist eine Headless-UI-Zustandsmaschinenbibliothek, die ungestylte Komponentenlogik bereitstellt, um konsistentes Verhalten über verschiedene Rendering-Engines hinweg sicherzustellen. Sie fungiert als Toolkit zur Modellierung komplexer User-Interface-Interaktionen unter Verwendung von Statecharts und entkoppelt die zugrunde liegende Logik und Accessibility-Attribute vom visuellen Styling. Die Bibliothek ist framework-agnostisch und nutzt spezialisierte Adapter, um ihre Zustandsmaschinenlogik mit verschiedenen JavaScript-Bibliotheken wie React, Solid, Vue und Svelte zu verbinden. Dieser Ansatz ermöglicht es Entwicklern, ein einheitliches Interaktionsmodell beizubehalten, während sie jede CSS- oder Styling-Lösung durch zustandsgesteuerte Datenattribute anwenden können. Zag deckt ein breites Spektrum an funktionalen Bereichen ab, einschließlich umfassendem Accessibility-Management für Tastaturnavigation und ARIA-Attribute sowie eine riesige Sammlung interaktiver Primitiven. Dazu gehören Input-Controls, Navigationselemente wie Menüs und Tabs, Overlay-Komponenten wie Dialoge und Popovers sowie komplexe Medienhandhabung für Bildzuschnitt und Signaturerfassung. Es bietet zudem Utilities für hierarchisches Datenmanagement, asynchrone Listenbehandlung und ein System zur Konstruktion geführter Produkttouren.

Basecoat is a zero-runtime UI library and themable interface framework consisting of a set of accessible web components. It provides a collection of pre-styled interface elements and utility classes designed to function as static assets without requiring a dedicated JavaScript framework runtime. The project features a dedicated UI component scaffolder, providing a command line interface to automate the generation of project folder structures and the installation of component templates. Visual styles are managed through a system of CSS variables and utility classes, allowing for global theme a
