Pure AngularJS based tree menu directive

In this tutorial I am going to share simple AngularJS directive to create tree menu. You must have seen tree menu on many control panel where you have to create nested menu – submenu – submenu and so on. These nested tree structure helps to associate list of submenu with parent menu.

Libraries

Copy the script and css into your project and add a script and link tag to your page.

<script type="text/javascript" src="/angular.treeview.js"></script>
<link rel="stylesheet" type="text/css" href="css/angular.treeview.css">

Add a dependency to your application module.

angular.module('myApp', ['angularTreeview']);

You can use following attribute to customize tree menu.

  • angular-treeview: the treeview directive.
  • tree-id : each tree’s unique id.
  • tree-model : the tree model on $scope.
  • node-id : each node’s id.
  • node-label : each node’s label.
  • node-children: each node’s children.

HTML

Here is a simple example.

<div
    data-angular-treeview="true"
    data-tree-id="abc"
    data-tree-model="treedata"
    data-node-id="id"
    data-node-label="label"
    data-node-children="children" >
</div>



Here is the tree menu structure.

$scope.treedata = 
[
    { "label" : "User", "id" : "role1", "children" : [
        { "label" : "subUser1", "id" : "role11", "children" : [] },
        { "label" : "subUser2", "id" : "role12", "children" : [
            { "label" : "subUser2-1", "id" : "role121", "children" : [
                { "label" : "subUser2-1-1", "id" : "role1211", "children" : [] },
                { "label" : "subUser2-1-2", "id" : "role1212", "children" : [] }
            ]}
        ]}
    ]},
    { "label" : "Admin", "id" : "role2", "children" : [] },
    { "label" : "Guest", "id" : "role3", "children" : [] }
];

JS

If tree node is selected, then that selected tree node is saved to $scope.”TREE ID”.currentNode. By using $watch, the controller can recognize the tree selection.

$scope.$watch( 'abc.currentNode', function( newObj, oldObj ) {
    if( $scope.abc && angular.isObject($scope.abc.currentNode) ) {
        console.log( 'Node Selected!!' );
        console.log( $scope.abc.currentNode );
    }
}, false);
