Change Portfolio/Masonry Sort Options to checkboxes

Hey Guys, very disappointed, I’m not paying support for get this templated answer. I think that is not complex question and answer. I have been forced in do a deep investigation in your code, this is my answer to my question:

First of all you need to know that i’m using a child theme because I want to update enfold in a future. I think (but not tested) that this code works in normal enfold functions.php but i wrote this code in child theme functions.php :

add_action( 'init', function () {
	
	//we need new portfolio class extending actual portfolio class
	class ebavs_portfolio extends avia_sc_portfolio {

		//this method is called when shortcode needs to render, we need override and then copy and paste original content 
		public function shortcode_handler($atts, $content = "", $shortcodename = "", $meta = "")
		{
			$atts['class'] = !empty($meta['custom_class']) ? $meta['custom_class'] : "";
			
			if(current_theme_supports('avia_template_builder_custom_post_type_grid'))
			{
			    if(isset($atts['link']))
			    {
			        $atts['link'] = explode(',', $atts['link'], 2 );
			        $atts['taxonomy'] = $atts['link'][0];
			
			        if(isset($atts['link'][1]))
			        {
			            $atts['categories'] = $atts['link'][1];
			        }
			    }
			
				if(empty($atts['post_type']) || !current_theme_supports('add_avia_builder_post_type_option'))
				{
					$atts['post_type'] = get_post_types();
				}

				if(is_string($atts['post_type'])) $atts['post_type'] = explode(',', $atts['post_type']);
			}
			
			$atts['fullscreen'] = ShortcodeHelper::is_top_level();

			// HERE WE CHANGE $grid TO NEW OBJECT
			$grid = new ebavs_post_grid($atts);
			$grid->query_entries();
			$portfolio_html = $grid->html();
		
			if(!ShortcodeHelper::is_top_level()) 
			return $portfolio_html . '<!-- ebavs -->';
			
			
			$params['class'] = "main_color avia-no-border-styling avia-fullwidth-portfolio ".$meta['el_class'];
			$params['open_structure'] = false;
			$params['id'] = !empty($atts['id']) ? AviaHelper::save_string($atts['id'],'-') : "";
			$params['custom_markup'] = $meta['custom_markup'];
			
			//we dont need a closing structure if the element is the first one or if a previous fullwidth element was displayed before
			if(isset($meta['index']) && $meta['index'] == 0) $params['close'] = false;
			if(!empty($meta['siblings']['prev']['tag']) && in_array($meta['siblings']['prev']['tag'], AviaBuilder::$full_el_no_section )) $params['close'] = false;
				
			$output  =  avia_new_section($params);
			$output .= $portfolio_html;
			$output .= avia_section_after_element_content( $meta , 'after_portfolio' );
			
			return $output . '<!-- ebavs -->';
		}

	}

	// Create new Grid class and extends the original
	class ebavs_post_grid extends avia_post_grid { 

		// override sort buttons, this methods render html for sort bar
		protected function sort_buttons($entries, $params)
		{
			//get all categories that are actually listed on the page
			$categories = get_categories(array(
				'taxonomy'	=> $params['taxonomy'],
				'hide_empty'=> 0
			));

			$current_page_cats 	= array();
			$cat_count 			= array();
			$display_cats 		= is_array($params['categories']) ? $params['categories'] : array_filter(explode(',',$params['categories']));

			foreach ($entries as $entry)
			{
				if($current_item_cats = get_the_terms( $entry->ID, $params['taxonomy'] ))
				{
					if(!empty($current_item_cats))
					{
						foreach($current_item_cats as $current_item_cat)
						{
							if(empty($display_cats) || in_array($current_item_cat->term_id, $display_cats))
							{
								$current_page_cats[$current_item_cat->term_id] = $current_item_cat->term_id;

								if(!isset($cat_count[$current_item_cat->term_id] ))
								{
									$cat_count[$current_item_cat->term_id] = 0;
								}

								$cat_count[$current_item_cat->term_id] ++;
							}
						}
					}
				}
			}

			// DRAW HERE YOUR HTML
			$output = 'new sort buttons';
			return $output;
			
		}

	}

	// Look for builder Avia Object
	global $builder;

	// Magic here, change portfolio class by our new class
	$builder->shortcode_class['avia_sc_portfolio'] = new ebavs_portfolio( $builder ); 
	
	// init new object
	$builder->shortcode_class['avia_sc_portfolio']->init();

	// and replace the named class for shortcode
	$builder->shortcode[$builder->shortcode_class['avia_sc_portfolio']->config['shortcode']] = 'ebavs_portfolio';

	// this shortcode have a heavy css and js components, you can add your new js and css in this point
},'100');

As you can see only few lines of code explaining how you can override portfolio sort buttons, masonry is similar.
