    $bootstrap_classes is a bunch of bootstrap classes (that I get form mb settings page through the function prefix_mega_menu_widget_classes()). I want to insert into 'before widget' but it doesn't work (it returns null). But when I try to print it out into a page, it works properly.

    I think, because widget init is prioritized, it runs before the setting function so the setting function (which I call in widget init function) returns null value.

    Could you help me, please! Thanks in advance <3

    function prefix_mega_menu_widget_classes() {
$option_name = 'prefix_options'; // update option_name
		$columns = rwmb_meta( 'mega-menu-columns', array( 'object_type' => 'setting' ), $option_name );
	if ( '4' === $columns ) {
		$classes = 'col-xl-3 col-lg-4 col-md-6';
	} elseif ( '3' === $columns ) {
		$classes = 'col-lg-4 col-md-6';
	} else {
		$classes = 'col-md-6';
	}

	return $classes;
}

function prefix_init_mega_menu_widgets() {
	$location  = 'mega-menu';
	$css_class = 'has-mega-menu';
	$locations = get_nav_menu_locations();
	if ( isset( $locations[ $location ] ) ) {
		$menu = get_term( $locations[ $location ], 'nav_menu' );
		if ( $items = wp_get_nav_menu_items( $menu->name ) ) {
			foreach ( $items as $item ) {
				if ( in_array( $css_class, $item->classes ) ) {

					$bootstrap_classes = prefix_mega_menu_widget_classes();

					register_sidebar( array(
						'id'            => 'mega-menu-widget-area-' . $item->ID,
						'name'          => $item->title . ' - Mega Menu',
						'before_widget' => '',
						'after_widget'  => '',
						'before_title'  => '<h3>',
						'after_title'   => '</h3>',
					) );
				}
			}
		}
	}
}
add_action( 'widgets_init', 'prefix_init_mega_menu_widgets' );

    Hi,

    As long as you saved theme settings, the settings is stored in the options table and of course, you can use the helper function to get it anytime you want, even before init hook. That's why when you print the value of the function prefix_mega_menu_widget_classes, it always work.

    I guess the problem is the way you register menu locations in your theme. It probably happens after widgets_init hook. FYI, widgets_init hook fires at init with priority 0. So, if you register your menu locations at init with priority 10, it will run *after* and doesn't work. Try to move the code to register menu locations to priority 0. (You still need to check to make sure it runs *before* widgets_init).

    Thank you Anh,
    I register my menu like this, it displays but the value from setting page doesn't seem to be passed in. am I doing it right?

    if ( ! function_exists( 'prefix_theme_setup' ) ) {
	function prefix_theme_setup() {
		// Nav Menus
		register_nav_menus( array(
			'mega-menu' => __( 'Mega Menu', 'textdomain' ) // Mega Menu
		) );
	}
}
add_action( 'after_setup_theme', 'prefix_theme_setup');

    Your code looks fine. I just found the problem. It's just the MB Settings Page is loaded at init with priority 5, which is later than widgets_init (fires at init with priority 0). So, to solve this problem, simply replace widgets_init with init!
