+# jstree
+
+[jsTree](http://www.jstree.com/) is jquery plugin, that provides interactive trees. It is absolutely free, [open source](https://github.com/vakata/jstree) and distributed under the MIT license.
+
+jsTree is easily extendable, themable and configurable, it supports HTML & JSON data sources, AJAX & async callback 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.
+
+You also get:
+ * drag & drop support
+ * keyboard navigation
+ * inline edit, create and delete
+ * tri-state checkboxes
+ * fuzzy searching
+ * customizable node types
