Issue I'm having is with trying to add column filters to fixed column headers. It works great when the filter is just a select, but when I use select2 the dropdown will not drop. (can test by commenting and uncommenting line 3 of js code) Is there a way to attach an event listener to the cloned select and have it fire the dropdown event on the original one or something of that nature to make this work?
