• jQuery v3.4.1 (>= 1.9.0)

Getting Started

or download manually.

Usage

Add the following resources for the bootstrap-treeview to function correctly.

<!-- Required Stylesheets -->
<link href="bootstrap.css" rel="stylesheet">

<!-- Required Javascript -->
<script src="jquery.js"></script>
<script src="bstreeview.js"></script>

The component will bind to any existing DOM element.

<div id="tree"></div>

Basic usage may look something like this.

function getTree() {
  // Some logic to retrieve, or generate tree structure
  return data;
}

$('#tree').bstreeview({ data: getTree() });

Data Structure

In order to define the hierarchical structure needed for the tree it's necessary to provide a nested array of JavaScript objects.

Example

var tree = [
  {
    text: "Node 1",
    icon: "fa fa-folder",
    nodes: [
      {
        text: "Sub Node 1",
        icon: "fa fa-folder",
        nodes: [
          {
            id:    "sub-node-1",
            text:  "Sub Child Node 1",
            icon:  "fa fa-folder",
            class: "nav-level-3",
            href:  "https://google.com"
          },
          {
            text: "Sub Child Node 2",
            icon: "fa fa-folder"
          }
        ]
      },
      {
        text: "Sub Node 2",
         icon: "fa fa-folder"
      }
    ]
  },
  {
    text: "Node 2",
    icon: "fa fa-folder"
  },
  {
    text: "Node 3",
    icon: "fa fa-folder"
  },
  {
    text: "Node 4",
    icon: "fa fa-folder"
  },
