Removing Browse fields

How can fields be removed from the Browse Special Block on All Members page (browse.php)?

For example, I would like to remove Age from the set of browsable fields (see attached image).

I've searched this site, but haven't found anything which clearly describes how to do this, especially on version 7+.

Any help greatly appreciated.

Thanks!

open file templates/base/scripts/BxBaseBrowse.php and find this code

// gen Age section ;
$sAgeSection  = _genAgeSection( $this, $sCurrentKey );   
if ( $sAgeSection ) {
$sVisibleParam = ( $this -> aParameters['age'] ) ? false : true;

$sAgeSection  =  _genSubDesignBox(
_genJsControlBox($sAgeCaption, 'age_section', $sVisibleParam),
$sAgeSection
);
}

Hide this code by edit it to this

// gen Age section ;
//$sAgeSection  = _genAgeSection( $this, $sCurrentKey );   
//if ( $sAgeSection ) {
//    $sVisibleParam = ( $this -> aParameters['age'] ) ? false : true;
//    $sAgeSection  =  _genSubDesignBox(
//        _genJsControlBox($sAgeCaption, 'age_section', $sVisibleParam),
//        $sAgeSection
//     );
//}

Tremendous!

Many thanks!
