There is no administrative option to change the column count in WooCommerce, but you can easily accomplish it by adding the following
PHP
code into your theme’s functions.php
file:
class ThemeFilters
{
function __construct()
{
add_filter('loop_shop_columns',array($this,'loop_shop_columns'));
}
function loop_shop_columns($cols)
{
return 3;
}
}
new ThemeFilters();
In this demonstration the columns are set to 3 but you can change it to 2 columns, 2 columns, or any number of columsn you desire. Change the return value return 3
above to meet you needs.
