Not sure how you are creating the search inputs but you can loop through the columns that won't have search inputs and set the html to an empty string. Use orderCellsTop to move the sorting function to the top header row. If you still need help please provide a link to your page or a test case showing how you are creating the header rows so we can help debug.

Your test case wasn't running due to errors. You were referencing a non-existent column in columnDefs and not loading the buttons JS code. I commented out the code not needed for the example:

I added orderCellsTop. The selector needed changed to apply the select lists to the second header and added a loop to empty the cells not containing the select input.
