Hi!
I can't figure out how to display my nested groups in the frontend.
I'm average in php.
Could you provide me the final php code to display this in the frontend with my params?
I hope your answer would be useful to all 'average php' users like me.
Thanks in advance...

Here is my functions.php

// Group
        array(
            
            'id'   => "{$prefix}sector",
            'type' => 'group',
            'clone'  => true,
	    'sort_clone' => false,
            'fields' => array(
	            
	            array(
			'name' => __( 'Name1', 'rw_' ),
			'id'   => "{$prefix}sector-heading",
			'type' => 'heading',
				
			),
	            
	            array(
			'name' => __( 'Name2', 'rw_' ),
			'id'   => "{$prefix}sector-title",
			'type' => 'textarea',
			'cols' => 10,
			'rows' => 1,
				
			),

                               // Group nested
				
				array(
            
				 'id'  => "{$prefix}sector-object",
				'type' => 'group',
				'clone'  => true,
				'sort_clone' => true,
				'fields' => array(
				
	            
						array(
						'name'  => __( 'Name3', 'rw_' ),
						'id'    => "{$prefix}sector-object-img",
						'type'  => 'image_advanced',
						'max_file_uploads' => 1,
						),
	            
						array(
						'name' => __( 'Name4', 'rw_' ),
						'id'   => "{$prefix}sector-object-description",
						'type' => 'textarea',
						'cols' => 10,
						'rows' => 4,
						),
			
			                   ),
				       ),
	            
                                    ),
                                  ),
	                        )
                             );

No problem, here you are:

<?php
$prefix = '';
$sectors = rwmb_meta( "{$prefix}sector" );
if ( ! empty( $sectors ) ) {
	foreach ( $sectors as $sector ) {
		$sector_heading = isset( $sector["{$prefix}sector-heading"] ) ? $sector["{$prefix}sector-heading"] : '';
		echo $sector_heading;

		$sector_title = isset( $sector["{$prefix}sector-title"] ) ? $sector["{$prefix}sector-title"] : '';
		echo $sector_title;

		$objects = isset( $sector["{$prefix}sector-object"] ) ? $sector["{$prefix}sector-object"] : array();
		foreach ( $objects as $object ) {
			$object_img = isset( $object["{$prefix}sector-object-img"] ) ? $object["{$prefix}sector-object-img"] : '';
			if ( $object_img ) {
				echo '<img src="' . wp_get_attachment_image_url( $object_img, 'size' ) . '">';
			}
			$object_desc = isset( $object["{$prefix}sector-object-description"] ) ? $object["{$prefix}sector-object-description"] : '';
			echo $object_desc;
		}
	}
}

Thanks for assistance, Anh Tran.
One more question.
What if my field is in nested group, has 10 images uploaded and is used as a slider in the frontend? How do I call these images?

array(
						'name'  => __( 'Name3', 'rw_' ),
						'id'    => "{$prefix}sector-object-img",
						'type'  => 'image_advanced',
						'max_file_uploads' => 10,
						),

I suppose there's something wrong with image_advanced field in nested groups.
I tried to exclude nested group, so for now my metabox looks like:

// Group
			array(
            'name' => 'Сектор инфраструктуры',
            'id'               => "{$prefix}sector",
            'type' => 'group',
            'clone'  => true,
			'sort_clone' => false,
            'fields' => array(
	            
	            
	            
	            array(
				'name' => __( 'Название сектора', 'rw_' ),
				
				'id'   => "{$prefix}sector-title",
				'type' => 'textarea',
				'cols' => 10,
				'rows' => 1,
				
				),
				
				array(
						'name' => __( 'Описание сектора', 'rw_' ),
						'id'   => "{$prefix}sector-description",
						'type' => 'textarea',
						'cols' => 10,
						'rows' => 4,
						),
				
					
				
	            array(
						'name'             => __( 'Изображение объекта', 'rw_' ),
						'id'               => "{$prefix}sector-object-image",
						'type'             => 'image_advanced',
						'max_file_uploads' => 10,
						),
	            
				
	            
            ),
        ),

And I call it in frontend

<?php $sectors = rwmb_meta( 'rw_sector' );
if ( ! empty( $sectors ) ) {
foreach ( $sectors as $sector )
{
    echo '<div class="object-block">
    
    		<div class="object">
    		
    			<div class="sector-object-text">';
    		
				$title = isset( $sector['rw_sector-title'] ) ? $sector['rw_sector-title'] : '';
		
				echo '<h3>' . $title . '</h3>';
    			
				$description = isset( $sector['rw_sector-description'] ) ? $sector['rw_sector-description'] : '';
		
				echo '<p>' .$description.'</p>';
				
					
				echo 
				'</div>';
    		
    		
				$object_img = isset( $sector['rw_sector-object-image'] ) ? $sector['rw_sector-object-image'] : '';
				if ( $object_img ) {
				
				echo 
				
				'<div class="sector-object-img">
						
					<div class="slider slider-for">
    		
							<img src="' . wp_get_attachment_image_url( $object_img, 'type=image_advanced&size=full&multiple=true' ) . '">
    		
					</div>
				</div>';
				}
    		
    		
    		
    echo	
    		
    		'</div>
		
		</div>';
	} 
} ?>

Title and description are displayed, but no images.
I even tried with 'max_file_uploads' => 1, but no luck

Ah, sorry, for image fields, the returned value is always an array. You need to change the code to:

$object_imgs = isset( $sector['rw_sector-object-image'] ) ? $sector['rw_sector-object-image'] : array();
if ( ! empty( $object_imgs ) ) {
    foreach ( $object_imgs as $object_img ) {
        echo '<div class="sector-object-img">
            <div class="slider slider-for">
            <img src="' . wp_get_attachment_image_url( $object_img, 'type=image_advanced&size=full&multiple=true' ) . '">
        </div>
        </div>';
    }
}
