  You can use the column-selector to choose the desired columns. Maybe use a class or an array of columns.

  Ok I used this but it didn't work.. I made an extra row in my thead to put the select fields into my Header and gave the rows which I want to search by options the classname "head".

  initComplete: function () {
                              var columns = table.columns('.head');
                              this.api().columns(columns)( function () {
                                  var column = this;
                                  var select = $('<select><option value=""></option></select>')
                                      .appendTo( $("#table thead tr:eq(1) th").eq(column.index()).empty() )
                                      .on( 'change', function () {
                                          var val = $.fn.dataTable.util.escapeRegex(
                                              $(this).val()
                                          );
  
                                          column
                                              .search( val ? '^'+val+'$' : '', true, false )
                                              .draw();
                                      } );
  
                                  column.data().unique().sort().each( function ( d, j ) {
                                      select.append( '<option value="'+d+'">'+d+'</option>' );
                                  } );
                              } );
                          },

  Instead of this:

                              var columns = table.columns('.head');
                              this.api().columns(columns)( function () {
  

  Try this:

                              this.api().columns('.head')( function () {
  

  The var columns contains an API instance which you are trying to pass to columns() in the second line. I don't think this is supported.

  Look at the browser's console for errors.

  I'm also trying to make the select Inputs without the 2nd row in my thead. Do you know if ist possible like this?

   var select = $('<select><option value=""></option></select>')
                                      .appendTo( $("#table thead tr th").eq(column.index()).empty() )

  Thanks for the test case. You had two issues. You didn't have the word every in this line:
  this.api().columns('.head').every( function () {

  This was causing the error message.

  The column class needs to be placed in the top header row since you have orderCellsTop: true,. This is the header row Datatables uses for its functions.

  Here is the updated working example with the above changes:
