# jsTree v.1.0

# cookies plugin

## Description

The `cookies` enables jstree to save the state of the tree across sessions. What this does is save the opened and selected nodes in a cookie, and reopen & reselect them the next time the user loads the tree. Depends on the jQuery.cookie plugin.

## Configuration

### save_opened

A string (or `false`). Default is `"jstree_open"`.

The name of the cookie to save opened nodes in. If set to `false` - opened nodes won't be saved.

### save_selected

A string (or `false`). Default is `"jstree_select"`.

The name of the cookie to save selected nodes in. If set to `false` - selected nodes won't be saved.

### auto_save

A Boolean. Default is `true`.

If set to `true` jstree will automatically update the cookies every time a change in the state occurs.

### cookie_options

An object. Default is `{}`.

The options accepted by the jQuery.cookie plugin.

## Demos
