Dropdown Tree with Bootstrap and jQuery, Easy implementation

Implement an interactive DropDownTree with user-friendly UI.

The DropDownTree is used to represent data in heirarchical structure, rendered in a tree-like structure, which provides multiple selection option and custom nodes.

Here we are implementing the dropdown tree with bootstrap and jquery with click handlers, data handlers. Single select and Multi-select enabled with children and ajax request for getting data.

The following example is taken from : https://github.com/JosephSKh/DropdownTree
