I have created a chart using Highcharts, which drilldown in the second click to show more information. In the first click, I can also select multiple charts using Shift+click or Ctrl+click. I also implemented a little div which appears when the user select one or more column and displays some information.
My trouble is: I want to implement this chart to iPad or any other portable device, so the user won't have shift or ctrl key. I want to create a multiple selection where first click selects as any chars the user click (and also unselect when clicks again) and the second click displays a drilldown, all keeping the structure I have. I know that is a fetched question but I will appreciate any help.

Jsfiddle: http://jsfiddle.net/ah7gzxth/
EDIT: I would like to implement the following jsfiddle in my chart, but I'm not able to achieve that goal. http://jsfiddle.net/3zy8p/58/
Summary:
I want to perform a multiple selection (similar than allowPointSelect:true) without using Shift+click/Ctrol+click in the first chart as well as in drilldowns implemented in my code.
Thanks to everyone!
