Yii2 bigmenu widget. Multilevel menu, PURE CSS

Any code contribution is welcome

Bigmenu renders a PURE CSS multilevel menu with advanced functions. It works like default nav widget, but dropdowns are pure css. It also allows large menu items loaded vía ajax using page parameter. It has no limit on levels, but be careful. A lot of levels are uncomfortable for users.

Installation

composer require eseperio/yii2-bigmenu-widget

When an item have page property and items, the first one will be available on medium-large devices meanwhile on second will be available on mobile devices.

              'url' => ['site/index'],
              'linkOptions' => [...],
          ],
          [
              'label' => 'Multilevel',
              'items' => [
                   ['label' => 'Level 1 - Dropdown A', 'url' => '#'],
                   '<li class="divider"></li>',
                   '<li class="dropdown-header">Dropdown Header</li>',
                   ['label' => 'Level 1 - Dropdown B', 'url' => '#'],
              ],
          ],
          [
              'label' => 'Login',
              'url' => ['site/login'],
              'visible' => Yii::$app->user->isGuest
          ],
          [
              'label' => 'Login',
              'url' => ['site/login'],
              'visible' => Yii::$app->user->isGuest,
              'page' => ['site/menu']
          ],
      ],
      'options' => ['class' =>'nav-pills'], // set this to nav-tab to get tab-styled navigation
      'jsOptions' => ['widthToEnableResponsive'=> 768], // set this to override the options used in js
  ]);

How to use

This widget is based on yii/bootstrap/nav widget yii\bootstrap\nav. The main differences are:

1. Allows infinite multilevel. For a better usability don´t use more than 3 levels.
2. Allow render a page as a menu panel. With this you are free to make complex and advanced dropdowns menus.
3. Render of pages in menu is made with ajax, and only one request is made per panel.

To use as simple multilevel pass an array to items property. See yii\bootstrap\nav documentation.

Dynamic panels

To use dynamic panels add to the menu item the property "page". This must be a link to the action that renders the page.

Bigmenu::widget([
   'hamburger' => "slide",
   'items' => [
      ['label'=>"Dynamic content", "url"=>["site/index"], "page"=>["site/samplemenupage"] ],
      ...
   ]
])

In your controller use eseperio\yii2-bigmenu\widget\BigmenuTrait. Then in your action, to render content call $this->renderBigmenu($view,$options).

Note: The trait only simplifies the task of differenciating render method, between render and renderAjax. So you can do this in your own controller if you don´t want to use traits.

Change hamburger

This widget implements Hamburgers by jonsuh. You can change the hamburger like this

Bigmenu::widget([
   'hamburger' => "slide",
   'items' => [...]
])

Change width to enable responsive

If you want custom the with of the responsive devise, you must set the property jsOptions

Bigmenu::widget([
  'jsOptions' => ['widthToEnableResponsive'=> 992],
   'items' => [...]
])
