Meta Box

Ok so I tried going the parent route

these are my main functions to add the menu pages and the fields

// Create Extensions Page
function bl_extensions_options_page( $settings_pages )
{
	$settings_pages[] = array(
		'id'            => 'builder-extensions',
		'option_name'   => 'builder_extensions',
		'menu_title'    => __( 'Page Builder Extensions', 'fl-builder' ),
		'icon_url'      => 'dashicons-images-alt',
		'submenu_title' => __( 'General', 'fl-builder' ), // Note this
	);
	return $settings_pages;
}
add_filter( 'mb_settings_pages', 'bl_extensions_options_page' );

// Add Fields to Extensions Page
function bl_extensions_options_meta_boxes( $meta_boxes )
{
	$meta_boxes[] = array(
		'id'             => 'options',
		'title'          => __( 'Extensions Options', 'fl-builder' ),
		'settings_pages' => 'builder-extensions',
        
		'fields'         => array(            
			array(
				'name' => __( 'Panel Name', 'fl-builder' ),
				'id'   => 'branding',
				'type' => 'text',
				'std'  => 'Extensions',
			),
            
			array(
				'name' => __( 'Enable Bootstrap', 'fl-builder' ),
				'id'   => 'bootstrap',
				'type' => 'checkbox',
			),            
		),
        
	);
	return $meta_boxes;
}
add_filter( 'rwmb_meta_boxes', 'bl_extensions_options_meta_boxes' );

and then to try an extend it I added this to the next plugin

// Create Extensions Page
function animated_text_settings_page( $settings_pages )
{
	$settings_pages[] = array(
		'id'          => 'animated-text-module',
		'option_name' => 'builder_extensions',
		'menu_title'  => __( 'Animated Text', 'fl-builder' ),
		'parent'      => 'builder-extensions',
	);	
	return $settings_pages;
	
}
add_filter( 'mb_settings_pages', 'animated_text_settings_page' );

// Add Fields to Extensions Page
function animate_module_fields( $meta_boxes )
{
	$meta_boxes[] = array(
		'id'             => 'animated_text',
		'title'          => __( 'Animated Text Options', 'fl-builder' ),
		'settings_pages' => 'animated-text-module',
        
		'fields'         => array(            
			array(
				'name' => __( 'Custom Field', 'fl-builder' ),
				'id'   => 'my_custom_field',
				'type' => 'text',
			),       
		),
        
	);
	return $meta_boxes;
}
add_filter( 'rwmb_meta_boxes', 'animate_module_fields' );

The issue with this setup is that the Animated Text appears as a sub menu to the parent item, but when I click on it, it takes me to a 404 page like this for example http://mydomain.com/wp-admin/animated-text-module

Well, the issue only occurs for themes it seems, because it does not have an issue when I use settings in plugins.

awesome, cheers

If I can work out how to get a LAMP stack or VVV running on Arch Linux, I would probably ditch Windows and DS for good...

But I am not that smart lol

I did that with no luck, but I have found the problem but not sure if I can fix it

I just uploaded the theme to a live site and it worked, so it appears to be an issue when working locally within DesktopServer...

Any thoughts on what the conflict may be then?

And the the settings.php file I have functions in are working because if I add it to the main functions.php it errors due to conflict as expected
