How to add 4 Columns instead of 3
Hi, Im using Vantage theme and it only allows 3 columns. I know that you can change the /includes/categories.php file [$args['menu_cols'] = ( $location == 'menu' ? 4 : 2 );] from 3:2 to 4:2 but im using a child theme.
How do I call this function in the functions.php file of my child theme?
