    'menu' => [
        'class' => 'mix8872\menu\Module',
        'on menuAfterCreate' => static function ($e) {
            $model = $e->model;
            // ... do something
        },
        'on menuAfterDelete' => static function ($e) {
            $model = $e->model;
            // ... do something
        },
        'on menuAfterUpdate' => static function ($e) {
            $model = $e->model;
            // ... do something
        },
        'on menuAfterSort' => static function ($e) {
            $model = $e->model;
            // ... do something
        },
        'on menuAfterAddItem' => static function ($e) {
            $model = $e->model;
            // ... do something
        },
        'on menuAfterDeleteItem' => static function ($e) {
            $model = $e->model;
            // ... do something
        },
    ],
    // ... other modules definition
],

Usage

After configuring go to the url /menu/default/index and press Add button,
fill the name, code and description of your new menu;

Now you can add menu items by pressing 'plus' green button in right side.
Menu items can be two types:

• simple
• from model

Simple

Simple menu item is the ordinary item with url and title. That's all.

From model

That's 'magic' menu item which get menu items from ActiveRecord model
and replaces itself with the received data.

This menu item has next not ordinary fields:

• Url - base url, unlike a 'Simple', it contains base and dynamic parts of url
  the dynamic part must be enclosed in curly brackets and must be the same as Url attribute
  for example: /news/{code}, here /news/ - is a basic part and {code} - is a dynamic part
  then Url attribute must declared as code
• Model class - here you should specify full model class name (of course with namespace)
• Url attribute - this is attribute name which will be used in the end part of url
• Title attribute - attribute from which the menu item title will be taken
  you can specify the name separated by a dot: content.title,
  then the value will be taken from the relative table, but you can set only one dot
• Description attribute - attribute from which the menu item description will be taken
  you can specify the name separated by a dot: content.description,
  then the value will be taken from the relative table, but you can set only one dot
• Selection parameters - there you can declare SQL-like parameters for selection of items from model
  for example: WHERE status = 1 ORDER BY id DESC LIMIT 2
  !!! BE CAREFUL, IT IS EXPERIMENTAL FEATURE AND CAN BREAK YOUR APP !!!

Next you may echo widget with its config.

The simplest case is:

<?= \mix8872\menu\widgets\MenuWidget::widget([
        'code' => 'Tx1rNy'
    ])
?>

But widget can be configured in more detail. Next options is available:

/**
 * Append class to the ul element
 * @var string
 */
public $menuClassName = '';

/**
 * Append id to the 'ul' element
 * @var string
 */
public $menuId = '';

/**
 * Append class to the all 'li' elements which are not parents or descendants
 * @var string
 */
public $itemsClassName = '';

/**
 * Append class to the all 'a' elements in the parent elements
 * @var string
 */
public $linkClassName = '';

/**
 * Append class to the all 'a' elements in the descendant elements
 * @var string
 */
public $sublinkClassName = '';

/**
 * Append class to the all descendant 'ul' elements
 * @var string
 */
public $submenuClassName = '';

/**
 * Append class to the all descendant 'li' elements
 * @var string
 */
public $subitemsClassName = '';

/**
 * Show description
 * @var bool
 */
public $description = false;

/**
 * Menu code
 * @var
 */
public $code;

/**
 * Active 'li' element class name
 * @var string
 */
public $activeClassName = 'active';

/**
 * Append class to the all parent 'li' elements
 * @var string
 */
public $parentClassName = '';

/**
 * Menu type: classic (default) or buttons
 * @var string
 */
public $type = 'classic';

/**
 * Tag to wrap submenu 'ul' element
 * @var
 */
public $submenuWrapperTag;

/**
 * Append class to submenu wrapper (submenuWrapperTag must defined)
 * @var string
 */
public $submenuWrapperClassName = '';

/**
 * If false (default) then parents elements has no links and shown as 'span'
 * @var bool
 */
public $isParentActive = false;

/**
 * Template for item 'a' elements which are not parents
 * @var string
 */
public $itemTemplate = '{link}';

/**
 * Template for item 'a' elements which are parents
 * @var string
 */
public $parentTemplate = '{link}';

/**
 * Template for all item 'a' elements
 * @var string
 */
public $linkTemplate = '{link}';

/**
 * Template title of all item 'a' elements
 * @var string
 */
public $linkTitleTemplate = '{url}';

/**
 * If true then current url will be excluded from menu, default false
 * @var bool
 */
public $exceptCurrent = false;

/**
 * Array of url's which must excluded from menu
 * @var array
 */
public $exceptItems = [];

Events

On adding, updating and deletion files will generates next events:

• EVENT_AFTER_CREATE = 'menuAfterCreate' - fires after creation new menu
• EVENT_AFTER_DELETE = 'menuAfterDelete' - fires after deletion menu
• EVENT_AFTER_DELETE_ITEM = 'menuAfterDeleteItem' - fires after deletion menu item
• EVENT_AFTER_ADD_ITEM = 'menuAfterAddItem' - fires after add menu item
• EVENT_AFTER_SORT = 'menuAfterSort' - fires after sort menu items
• EVENT_AFTER_UPDATE = 'menuAfterUpdate' - fire after update menu,
  also fires when EVENT_AFTER_ADD_ITEM, EVENT_AFTER_DELETE_ITEM and EVENT_AFTER_SORT

You can intercept events in the module configuration as in the example above.
