Customize filter for adding new function

Hello,
this is the 7th site with your theme and i need to customize filter type in Elementor with adding just 1 level of “Categories”, not ancestors. So, for now i’ve found the file “class-product-filters.php” in “Elements” of integrations and started customization. I’ve opened this topic for 2 reasons:

1) I think can is a new amazing features can u add to your amazing theme;
2) I need some help with finish my customization, if u can…

So, i’ve found the function and on line 132 i’ve customized the code:

		$repeater->add_control(
			'filter_type',
			[
				'label'   => esc_html__( 'Filter type', 'woodmart' ),
				'type'    => Controls_Manager::SELECT,
				'options' => [
		MY CUSTOMIZATION---->	'sono'		 => esc_html__( 'Sono' ),
					'categories' => esc_html__( 'Categories', 'woodmart' ),
					'attributes' => esc_html__( 'Attributes', 'woodmart' ),
					'stock'      => esc_html__( 'Stock status', 'woodmart' ),
					'price'      => esc_html__( 'Price', 'woodmart' ),
				],
				'default' => 'categories',
			]
		);

		/**
		 * MY CUSTOMIZATION "Sono settings". I use your code for autocomplete, so integrated with your existing function.
		 */

		$repeater->add_control(
			'sono',
			[
				'label'       => esc_html__( 'Categories', 'woodmart' ),
				'description' => esc_html__( 'List of product categories.', 'woodmart' ),
				'type'        => 'wd_autocomplete',
				'search'      => 'woodmart_get_taxonomies_by_query',
				'render'      => 'woodmart_get_taxonomies_title_by_id',
				'taxonomy'    => 'product_cat',
				'multiple'    => true,
				'label_block' => true,
				'condition'	  => [
					'filter_type' => 'sono',
				],
			]
		);

For now, no problem. But for add really my function and show my customization, i need to change on line 401:

		/**
		 * Repeater settings.
		 */
		$this->add_control(
			'items',
			[
				'type'        => Controls_Manager::REPEATER,
				'title_field' => '{{{ filter_type }}}',
				'fields'      => array_values( $repeater->get_controls() ),
				'default'     => [
					[
MY CUSTOMIZATION----->				'filter_type' => 'sono'
					],
					[
						'filter_type' => 'categories',
					],
					[
						'filter_type' => 'attributes',
					],
					[
						'filter_type' => 'stock',
					],
					[
						'filter_type' => 'price',
					],
				],
			]
		);

And on line 515:

		<form <?php echo $this->get_render_attribute_string( 'wrapper' ); ?>>
			<?php foreach ( $settings['items'] as $index => $item ) : ?>
				<?php if ( 'categories' === $item['filter_type'] ) : ?>
					<?php $this->categories_filter_template( $item ); ?>
MY CUSTOMIZATION---->		<?php elseif ( 'sono' === $item['filter_type'] ) : ?>
					<?php $this->sono_filter_template( $item ); ?>
				<?php elseif ( 'attributes' === $item['filter_type'] ) : ?>
					<?php $this->attributes_filter_template( $item ); ?>
				<?php elseif ( 'stock' === $item['filter_type'] ) : ?>
					<?php $this->stock_filter_template( $item ); ?>
				<?php elseif ( 'price' === $item['filter_type'] ) : ?>
					<?php $this->price_filter_template( $item ); ?>
				<?php endif; ?>
			<?php endforeach; ?>

			<div class="woodmart-pf-btn">
				<button type="submit">
					<?php esc_html_e( 'Filter', 'woodmart' ); ?>
				</button>
			</div>
		</form>
		<?php
	}

And for show on frontend, on line 538 i’ve added my public_function:

	public function sono_filter_template( $settings) {
		$default_settings = [
			// Query.
			'sono_title'			 => esc_html__( 'Sono...', 'woodmart' ),
			'number'                 => null,
			'orderby'                => '',
			'order'                  => 'ASC',
			'ids'                    => '',
			'show_categories'		 => '',
		];

		$settings = wp_parse_args( $this->get_settings_for_display(), $default_settings );

		// Query.
		$query_args = array(
			'taxonomy'   => 'product_cat',
			'order'      => $settings['order'],
			'include'    => $settings['ids'],
			'pad_counts' => true,
			'number'     => $settings['number'],
		);

		if ( $settings['orderby'] ) {
			$query_args['orderby'] = $settings['orderby'];
		}

		$categories = get_terms( $query_args );
?>
		<div class="woodmart-pf-checkboxes woodmart-pf-categories">
			<div class="woodmart-pf-title">
				<span class="title-text">
					<?php echo esc_html( $settings['sono_title'] ); ?>
				</span>
				
				<ul class="woodmart-pf-results"></ul>
			</div>
		
			<div class="woodmart-pf-dropdown woodmart-scroll">
				<ul class="woodmart-scroll-content">
					<?php if ( $settings['show_categories'] ) : ?>
						<li style="display:none;" class="pf-active cat-item cat-item-<?php echo $current_cat->term_id; ?>">
							<a class="pf-value" href="<?php echo esc_url( get_category_link( $product_cat->term_id ) ); ?>" data-val="<?php echo esc_attr( $current_cat->slug ); ?>" data-title="<?php echo esc_attr( $current_cat->name ); ?>">
								<?php echo esc_html( $current_cat->name ); ?>
							</a>
						</li>
					<?php endif; ?>
					
					<?php echo wp_list_categories( $query_args ); ?>
				</ul>
			</div>
		</div>
<?php
	}
