Change Filter behavior

Seppelchen

Hello,

we are using this Code:

aoColumns: [ null,
{ sSelector: "#filter_a", type: "date-range" },
{ sSelector: "#filter_b", type: "select", values: [ <?php echo getpilotname(); ?> ] },
null,
null,
null,
null,
null,
null,
null,
null
]

    });

    var $options = $("#filter_b").find("select  > option").clone();

             $('#pilotnames')
             .empty()
             .append($options);

It will output all Names.
How it is possible that we change select box to a special value who no one could change?
I mean how it is possible to insert the filter_b value with no selector?

So How it is possible to replace the type "select" to a fix value?
