README

Yii 2.0 implementation of tree table behavior using jquery-treetable plugin. Provides a Gridview like widget.

• jquery-treetable - http://ludo.cubicphuse.nl/jquery-treetable/

Installation

The preferred way to install this extension is through composer.

Either run

$ php composer.phar require agtong/yii2-treetable

or add

"agtong/yii2-treetable": "*"

to the require section of your composer.json file.

Usage

Use agtong\treetable\Treetable widget instead of a Yii Gridview. The example below will collapse every even row in the table below the odd one above it.

    <?= Treetable::widget([
        'dataProvider' => $dataProvider,
        'rowOptions' => function($model, $key, $index, $grid) {
            if ($index % 2) {
                return ['data-tt-id' => $index, 'data-tt-parent-id' => $index-1];
            } else {
                return ['data-tt-id' => $index];
            }
        },
        'treetableOptions' => ['expandable' => true, 'indent' => 0], //Pass configuration options to $().treetable()
        // 'useOwnCss' => true, // default is false.
        // eg. add to view -> $this->registerCssFile(Yii::getAlias('@web') . '/css/your_own_treetable.css');
        'columns' => [
            ...
        ]
    ]); ?>

Read the documentation on treetable (http://ludo.cubicphuse.nl/jquery-treetable/) to understand how working with the data-tt-id and data-tt-parent-id can determine the nesting. A function for rowOptions as shown above can work with your datamodel to nest as you like.

Tip

Not all CSS from treetable is included because it breaks heavilly with Bootstrap layout. A css example is included to style the expand/collapse <a> with an image. Take a look at the CSS provided with jquery-treetable for more inspiration.
