FAQ

Do I need to add code to my theme’s `functions.php` file?

No, you don’t. This plugin just works(TM). However, you will need to add the style for the classes you use for your widgets.

Is there any known bug?

In short, maybe. If your theme or one of your plugins is replacing the default widget callback in a weird way, this plugin may not work.

Do you provide filters?

YES! You can hook into widget_attribute_id and/or widget_attribute_classes if you need to validate/sanitize the attributes provided by the user. For example:

/**
 * Check for widget classes provided by the user
 *
 * @param string $classes Widget class(es), separated by spaces
 */
function my_widget_classes_filter( $classes ) {
    // do your thing...
    return $classes;
}
add_filter( 'widget_attribute_classes', 'my_widget_classes_filter' );
