Why Select_Plus_CMB2_Types class?

• This enables you to use it flexibly in case you need to just render the field, not the whole row.
• It allows you to override the default args of the field

// field args
$args = array(
    'field_args'    => array(
        'id'        => 'some_id_here',
        'type'      => 'select_plus',
        'options'   => array(
            'standard' => 'Option One',
            'custom'   => 'Option Two',
            'none'     => 'Option Three',
        ),
) );
// create field
$field = new CMB2_Field( $args );

// pass the field to custom class
$types = new Select_Plus_CMB2_Types( $field );

// render the field with new id and name
echo $types->select_plus( array(
    'id'    => 'new_id_0_here',
    'name'  => 'smart[param][value]',
) );
