[![ScreenShot](https://github.com/eu81273/angular.treeview/raw/master/img/preview.png)](https://jsfiddle.net/eu81273/8LWUc/)

## Installation

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

```html
<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.

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

Add a tree to your application. See [Usage](#usage).

## Usage

Attributes of angular treeview are below.

- 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.

Here is a simple example.


```html
<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>
```

Example model:

```javascript
$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" : [] }
];	 
```

## Selection

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.


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