See also yii\helpers\Html::renderTagAttributes() for details on how attributes are being rendered.

public array $itemOptions = []
$items public property

List of selectable items. Each item can be a string representing the item content or an array of the following structure:

    [
        'content' => 'item content',
        // the HTML attributes of the item container tag. This will overwrite "itemOptions".
        'options' => [],
    ]

public array $items = []
$mode public property

The mode used to render the widget.

public string $mode = self::MODE_DEFAULT
$options public property

The HTML attributes for the widget container tag. The following special options are recognized:

- tag: string, defaults to "ul", the tag name of the container tag of this widget.

See also yii\helpers\Html::renderTagAttributes() for details on how attributes are being rendered.

public array $options = []

## Method Details

begin() public static method

Begins a widget.

This method creates an instance of the calling class setting the MODE_BEGIN mode. Any item between begin() and end() which match the filter attribute, will be selectable. It will apply the configuration to the created instance. A matching end() call should be called later. As some widgets may use output buffering, the end() call should be made in the same view to avoid breaking the nesting of output buffers.

See also end().

public static static begin ( $config = [] )
$config | array | Name-value pairs that will be used to initialize the object properties
return | static | The newly created widget instance

init() public method

Initializes the widget.

public void init ( )

renderItems() public method

Renders selectable items as specified on $items.

public string renderItems ( )
return | string | The rendering result.
throws | \yii\jui\InvalidConfigException. |

run() public method

Renders the widget.

public void run ( )
