JQWidgets
jQWidgets is a software framework with widgets (graphical control elements), themes, input validation, drag & drop plug-in, data adapters, built-in WAI-ARIA accessibility, internationalization and MVVM support. It is built on the open standards and technologies HTML5, CSS, JavaScript and jQuery. This library is used for developing responsive web and mobile applications. Some developers consider jQWidgets one of the top alternatives to the open source jQuery UI.
Some notable users of jQWidgets include Green Card Program USA, the French citizen portal Vie-publique.fr, the University of Iowa and the University of Maryland. The framework is also used in NSB/AppStudio.
