bootstrap jquery ajax tree treeview krajee hierarchy nested set nestedset

yii2-tree-manager

An enhanced tree management module from Krajee with tree node selection and manipulation using nested sets. The extension features are listed below:

A complete tree management solution which provides ability to manage hierarchical data stored using nested sets. Utilizes the yii2-nested-sets extension to manage the tree structure in your database. Refer the documentation for yii2-nested-sets extension before you start using this module.
A tree view built from scratch entirely without any third party plugins. The TreeView is designed using HTML5, jQuery & CSS3 features to work along with Yii PHP framework.
Styled with CSS3, includes jquery transitions and loading sections for ajax content, includes embedded alerts, and utilizes bootstrap css.
Tree management feature options and modes:
- View, edit, or administer the tree structure using TreeView widget as a selector and a dynamically rendered form to edit the tree node
- The form works as both a detail view for the node OR as a management tool to add/edit/delete the node.
- Form is rendered via ajax. It intelligently uses caching when the same node is clicked again (unless, the nodes are modified).
- Unique Admin Mode for allowing administrator actions on tree.
- Ability to add, edit, or delete tree nodes
- Ability to reorder tree nodes (move up, down, left or right).
- Configure tree node icons, styles, and ability to add checkboxes to tree nodes
- i18N translations enabled across the module.
Includes various jquery plugin events for advanced usage that are triggered on various tree manipulation actions.
Bonus: Includes a TreeViewInput widget that allows you to use the treeview as an input widget. The TreeViewInput widget is uniquely designed by Krajee (using jQuery & PHP with HTML5/CSS) to appear as a dropdown selection menu. It allows multiple selection or single selection of values/nodes from the tree.
A Tree model that builds upon the yii2-nested-set model and is made to be easily extensible for various use cases. It includes prebuilt flags for each tree node. Check the Tree Model documentation for more.
active: whether a tree node is active (if soft delete is enabled, the tree node will be just inactivated instead of deleting from database).
selected: whether a tree node is selected by default.
disabled: disables a tree node for editing or reorder
readonly: a read only tree node that prevents editing, but can be reordered or moved up/down
visible: whether a tree node is visible by default.
collapsed: whether a tree node is collapsed by default.
movable_u: whether a tree node is allowed to be movable up.
movable_d: whether a tree node is allowed to be movable down.
movable_l: whether a tree node is allowed to be movable left.
movable_r: whether a tree node is allowed to be movable right.
removable: whether a tree node is removable - will not be removed if children exist. If soft delete is enabled, then the node will be inactivated - else removed from database.
removable_all: whether a tree node is removable with children. If soft delete is enabled, then the node and its children will be inactivated - else removed from database.

The following important PHP classes are available with this module:

kartik\tree\Module: Module, allows you to configure the module. You must setup a module named treemanager. Refer documentation for details.
kartik\tree\TreeView: Widget, allows you to manage the tree in admin mode or normal user mode with actions and toolbar to add, edit, reorder, or delete tree nodes.
kartik\tree\TreeViewInput: Widget, allows you to use the treeview as a dropdown input either as a single select or multiple selection.
kartik\tree\models\Tree: Model, the entire tree data structure that uses the Nested set behavior from yii2-nested-sets to manage the tree nodes.
kartik\tree\models\TreeQuery: Query, the query class as required for the Nested set model.
kartik\tree\controllers\NodeController: Controller, the controller actions that manages the editing of each node for create, update, delete, or reorder (move).

Demo

You can see detailed documentation, API Code Documentation and TreeView demonstration or TreeViewInput demonstration on usage of the extension.

Installation

The preferred way to install this extension is through composer.

NOTE: Check the composer.json for this extension's requirements and dependencies. Read this web tip /wiki on setting the minimum-stability settings for your application's composer.json.

Either run

$ php composer.phar require kartik-v/yii2-tree-manager "@dev"

or add

"kartik-v/yii2-tree-manager": "@dev"

to the require section of your composer.json file.

Usage

Step 1: Prepare Database

Create your database table to store the tree structure. You can do it in one of the following ways:

Option 1: Run DB Migrations

You can run the migrations script provided to create the database structure from your yii programming console:

php yii migrate/up --migrationPath=@vendor/kartik-v/yii2-tree-manager/src/migrations

Option 2: Executing SQL script

Alternatively, you can execute the SQL script to generate your DB structure. Copy and modify the migrations/tree.sql file (a MySQL example), to create the table tbl_tree (or for any table name you need).

NOTE: You can add columns you need to this table, but you cannot skip/drop any of the columns mentioned in the script. You can choose to rename the id, root, lft, rgt, lvl, name, icon, icon_type columns if you choose to - but these must be accordingly setup in the module.

Step 2: Setup Model

Create your model for storing the tree structure extending kartik\tree\models\Tree class. You can alternatively build your own model extending from yii\db\ActiveRecord but modify it to use the kartik\tree\models\TreeTrait. You must provide the table name in the model. Optionally you can add rules, or edit the various methods like isVisible, isDisabled etc. to identify allowed flags for nodes.

So when extending from the \kartik\tree\models\Tree, you can set it like below:

namespace frontend\models;

use Yii;

class Tree extends \kartik\tree\models\Tree
{
    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return 'tbl_tree';
    }    
}

Alternatively, you can configure your model to not extend from kartik\tree\models\Tree and instead implement and use the kartik\tree\models\TreeTrait:

namespace frontend\models;

use Yii;

class Tree extends \yii\db\ActiveRecord
{
    use kartik\tree\models\TreeTrait;

    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return 'tbl_tree';
    }    
}

Step 3: Setup Module

Configure the module named treemanager in the modules section of your Yii configuration file.

'modules' => [
   'treemanager' =>  [
        'class' => '\kartik\tree\Module',
        // other module settings, refer detailed documentation
    ]
]

Step 4: Using TreeView Widget

In your view files, you can now use the tree view directly to manage tree data as shown below:

use kartik\tree\TreeView;
echo TreeView::widget([
    // single query fetch to render the tree
    'query'             => Tree::find()->addOrderBy('root, lft'), 
    'headingOptions'    => ['label' => 'Categories'],
    'isAdmin'           => false,                       // optional (toggle to enable admin mode)
    'displayValue'      => 1,                           // initial display value
    //'softDelete'      => true,                        // normally not needed to change
    //'cacheSettings'   => ['enableCache' => true]      // normally not needed to change
]);

Step 5: Using TreeViewInput Widget

If you wish to use the tree input to select tree items, you can use the TreeViewInput widget as shown below. Normally you would use this as a dropdown with the asDropdown property set to true. If asDropdown is set to false, the treeview input widget will be rendered inline for selection.

use kartik\tree\TreeViewInput;
echo TreeViewInput::widget([
    // single query fetch to render the tree
    'query'             => Tree::find()->addOrderBy('root, lft'), 
    'headingOptions'    => ['label' => 'Categories'],
    'name'              => 'kv-product',    // input name
    'value'             => '1,2,3',         // values selected (comma separated for multiple select)
    'asDropdown'        => true,            // will render the tree input widget as a dropdown.
    'multiple'          => true,            // set to false if you do not need multiple selection
    'fontAwesome'       => true,            // render font awesome icons
    'rootOptions'       => [
        'label' => '<i class="fa fa-tree"></i>', 
        'class'=>'text-success'
    ],                                      // custom root label
    //'options'         => ['disabled' => true],
]);
