Manage Dashboard Columns

In the latest versions of WordPress, the number of columns showing in the dashboard are automatically generated based on your screen size. That works for many situations, but you may want to control the number of columns.

For example, if  you only have 1 or 2 items showing on your dashboard, it looks awkward on a large screen. So, here is a function that allows you to control the default and max number of columns:

function lt_dashboard_columns() {
    add_screen_option(
        'layout_columns',
        array(
            'max'     => 2,
            'default' => 1
        )
    );
}
add_action( 'admin_head-index.php', 'lt_dashboard_columns' );
