combining form_dropdown() und set_select()

I don't think it is true that you must set an accompanying rule. I do this without and it works in an add/edit scenario

Code:

$selectname = "myselect";
        $options = array(
                    ""=>'Choose',
                    "option1"=>"option1",
                    "option2"=>"option2",
                    "option3"=>"option3"
                    );
        echo form_dropdown( $selectname, $options, set_value( $selectname, $$selectname ) );

Quick, easy and very helpful for large forms
