drilldown js issue

[xiandalisay]

I tried using pie chart with dill down. I passed the JSON data. I also tried using array format. But the drill down does not work. Do I have the bypass the needed js assets?

This is from the demo http://www.highcharts.com/demo/pie-drilldown

@xiandalisay sorry for the delayed response. If you have not already solved the issue yourself, the key is to specify any additional js files you need using the scripts property like this:

<?= \miloschuman\highcharts\HighCharts::widget([
    'scripts' => ['modules/drilldown'],
    'options' => '{...}',
]); ?>

This behavior is documented in the Tips section of Readme.md
