jsTree is jquery plugin, that provides interactive trees. It is absolutely free, open source and distributed under the MIT license. jsTree is easily extendable, themable and configurable, it supports HTML & JSON data sources and AJAX loading.
jsTree functions properly in either box-model (content-box or border-box), can be loaded as an AMD module, and has a built in mobile theme for responsive design, that can easily be customized. It uses jQuery’s event system, so binding callbacks on various events in the tree is familiar and easy.
Owl Carousel tops the list of jQuery carousel plugins for creating functional and responsive sliders.
The plugin boasts extensive customisation options including responsive modes (number of slides to display at certain breakpoints), merge options for slides with different widths and CSS-based transitions between slides.
