Control Wrapper - Drop Down List

[josep...@gmail.com]

Hi,

I am new to Google Charts. I have been using control wrapper function to filter data. I have been using the following function.

programmaticSlider = new google.visualization.ControlWrapper({

          'controlType': 'NumberRangeFilter',

 'containerId': 'programmatic_control_div',

          'options': {

            'filterColumnLabel': 'Year',

            'ui': {'labelStacking': 'vertical'}

          }

        });

But I would like to replace the slider with a drop-down list based on the values of a column. Could someone please help me with this ?
