Adding Row settings to WPBakery plugin - php

Question

How do I get the settings to the frontend? I need to add classes to vc_row.
/**
* Ken Burns Effect for Row.
*/
add_action( 'vc_after_init', 'ken_burns_effect_add_option_to_vc_row' );
function ken_burns_effect_add_option_to_vc_row() {
// Ken Burns Effect Attributes
$ken_burns_effect_attributes =
array(
array(
'type' => 'checkbox',
'heading' => __( 'Ken Burns for image background', 'ken_burns_effect' ),
'param_name' => 'enable_ken_burns_effect',
'value' => array(
__( 'Yes', 'ken_burns_effect' ) => 'yes',
),
'description' => 'Check this box if you want to enable ken burns effect for this row.',
),
array(
'type' => 'dropdown',
'heading' => __( 'Direction', 'ken_burns_effect' ),
'param_name' => 'direction_ken_burns_effect',
'value' => array(
'Zoom In' => 'zoom_in',
'Zoom Out' => 'zoom_out',
),
'description' => __( '', 'ken_burns_effect' ),
'dependency' => array(
'element' => 'enable_ken_burns_effect',
'value' => array( 'yes' ),
),
),
array(
'type' => 'textfield',
'heading' => __( 'Transition speed', 'ken_burns_effect' ),
'param_name' => 'transition_speed_ken_burns_effect',
'value' => '',
'description' => __( '', 'ken_burns_effect' ),
'dependency' => array(
'element' => 'enable_ken_burns_effect',
'value' => array( 'yes' ),
),
),
);
vc_add_params( 'vc_row', $ken_burns_effect_attributes);
}

You will have to override the vc_row.php by copying it to your theme or plugin.
You can check their documentation on how to set the override directory: https://kb.wpbakery.com/docs/inner-api/vc_set_shortcodes_templates_dir/
Then you can use your custom params inside vc_row.php using their param_name eg:
$enable_ken_burns_effect;
$direction_ken_burns_effect;
$transition_speed_ken_burns_effect;
Keep in mind that you have to override vc_row_inner.php too if you want to use options there. Same goes for section and columns.
