Today I had glanced over Kendo UI, jQuery UI and jsTree.
Kendo UI is a charging software. Kendo UI has it all: rich jQuery-based widgets, a simple and consistent programming interface, a rock-solid DataSource, validation, internationalization, a MVVM framework, themes, templates .
jQuery UI is a curated set of user interface interactions, effects, widgets, and themes built on top of the jQuery JavaScript Library. Whether you're building highly interactive web applications or you just need to add a date picker to a form control, jQuery UI is the perfect choice.
jsTree is a javascript based, cross browser tree component. It is packaged as a jQuery plugin. jsTree is absolutely free.
