How to get short description under heading – Visual Composer [closed]

I got resolution,

vc_map( array(
        "name" => __( "xxxxxx" ),
        "base" => "xxxxx",
        "icon" => plugins_url('img/vc-icon.png', __FILE__),
        'description' => __( 'xxxxxxxx', 'xxxxxxxxxx' ),
        "params" => array(
            array(
                'type' => 'dropdown',
                'heading' => __( 'Select xxxxxx', 'xxxxxxxxxx' ),
                'param_name' => 'id',
                'admin_label' => true,
                'value' => $xxxxcvx
            ),
        ),
    ) );

I implemented 'admin_label' => true, and then it’s working fine….
