WordPress 3.8 – Dashboard 1 Column Screen Options

With the new WordPress 3.8 under Screen Options they seem to have misplaced the “Columns” feature where you could put your widgets into 1 Column, 2 Columns, 3 Columns, or 4 Columns. My question is how to I force my Dashboard Widgets to only be 1 column, or in other words, take up the whole width of the screen versus just a portion of the screen?

Method 1

Another solution is to add the columns setting back to the settings.

function wpse126301_dashboard_columns() {
    add_screen_option(
        'layout_columns',
        array(
            'max'     => 2,
            'default' => 1
        )
    );
}
add_action( 'admin_head-index.php', 'wpse126301_dashboard_columns' );

Method 2

This happens because of the new media queries. A very unfortunate change …

Anyway, you can change it by setting a custom width for .postbox-container.

Use 50% for two columns and 100 % for just one column.

add_action( 'admin_head-index.php', function()
{
    ?>
<style>
.postbox-container {
    min-width: 100% !important;
}
.meta-box-sortables.ui-sortable.empty-container { 
    display: none;
}
</style>
    <?php
});
