BloX - Dropdown list as a dashboard filter

Hi intapiuser ,

Thank you for the script and the example for this Blox dropdown, unfortunately, I cannot click on the button or make any selections. Do you know why this would be? I am using the exact script you provided and saved the template as a JSON file. When the template shows up I can pick and use what field I want the filter option to be but when I apply this filter Blox Widget, I cannot make another selection.
