If you want a multilevel drilldown you have to set id of the drilldown to the data point just like in the pure js highcharts.

Example: http://jsfiddle.net/6LXVQ/2/ and the most important part:

drilldown: {
        series: [{
            id: 'animals',
            name: 'Animals',
            data: [{
                name: 'Cats',
                y: 4,
                drilldown: 'cats'
            }, ['Dogs', 2],
                ['Cows', 1],
                ['Sheep', 2],
                ['Pigs', 1]
            ]
        }, {

            id: 'cats',
            data: [1, 2, 3]
        }]
    }

You can see here that your data points are not only numbers but objects which containts link to the drilldown series.

An example using Highcharter - simplified but you should get the idea:

hc <- highchart() %>%
    hc_chart(type="column") %>%
    hc_xAxis(type="category") %>%
    hc_add_series(
        name = "Things",
        data = list(
            list(
                name = "Animals",
                y = 10,
                drilldown = "animals"
            )
        )
    ) %>%

    hc_drilldown(
        series = list(
            list(
                name = "Animals",
                id = "animals",
                data = list(
                    list(
                        name = "Cats",
                        y = 2,
                        drilldown = "cats"
                    )
                )
             ),
             list(
                 name = "Cats",
                 id = "cats",
                 data = list(list(name = "white cats", y = 2), list(name = "black cats", y = 3), list(name = "red cats",y = 4))
             )
         )
     )
