Add a New Footer Widgets Column

/**
 * Add your own footer widgets columns
 * Add a number between 1 to 7
 */
function my_footer_widgets_columns() {

	// Add your column number
	$columns = '5';

	// Return
	return $columns;

}
add_filter( 'ocean_footer_widgets_columns', 'my_footer_widgets_columns' );

/**
 * Create a new footer widget area
 */
function my_footer_widget_area() {

	// Footer 5
	register_sidebar( array(
		'name'			=> esc_html__( 'Footer 5', 'oceanwp' ),
		'id'			=> 'footer-five',
		'description'	=> esc_html__( 'Widgets in this area are used in the fifth footer region.', 'oceanwp' ),
		'before_widget'	=> '<div class="footer-widget %2$s clr">',
		'after_widget'	=> '</div>',
		'before_title'	=> '<h6 class="widget-title">',
		'after_title'	=> '</h6>',
	) );

}
add_action( 'widgets_init', 'my_footer_widget_area', 11 );

Then, follow these steps to add this new column to the footer:

1

Create a partials folder in your child theme, in this folder, create another one named footer.

2

Copy the widgets.php file from oceanwp/partials/footer/ in the same folder of the child theme.

3

Open this file in your text editor and add the following code after the Footer box 4:

<div class="footer-box <?php echo esc_attr( $grid_class ); ?> col col-5">
	<?php dynamic_sidebar( 'footer-five' ); ?>
</div><!-- .footer-box -->
