Answer 1

After a long research in Web I found the answer for my own question:

$this->addDisplayGroup(array('DATEFROM','DATETO'),
                                       'contact',array('legend' => 'Contact Information'));

$from_to = $this->getDisplayGroup('contact');
$from_to->setDecorators(array('FormElements',
  array(array('openinnerdiv' => 'HtmlTag'),
  array('tag' => 'div', 'id'=>'date_1','name'=>'date_1','class'=>'date_1','openOnly'=>true)),
  array(array('opendiv6' => 'HtmlTag'),
  array('tag' => 'div','id'=>'blockfld_1','class'=>'blockfld','openOnly'=>true)),
  array(array('opendiv' => 'HtmlTag'),
  array('tag' => 'div','id'=>'block','openOnly'=>true)),                                                                        
));


$this->addDisplayGroup(array('AddBlock','Add','AddDate','NUMBERPLATE','COUNTRYCODE','NODE','CAMERA','NODELIST','NODECAMERA'),
       'pass',array('legend' => 'Password')); 

$pass = $this->getDisplayGroup('pass');
 $pass->setDecorators(array(
        'FormElements',
         array('HtmlTag',array('tag'=>'div','closeOnly'=>true))
));

I just modified for the answer so some small mistakes will be there kindly correct it.
