[Ivan]

<form role="search" method="get" id="searchform" action="<?php echo home_url( '/' );?>" class="search-form">
	<input type="text" value="<?php echo get_search_query(); ?>" name="s" id="s" class = "input1" placeholder = "..." />
	<?php if (class_exists('WooCommerce')) : ?>
	
		<?php
		if(isset($_REQUEST['product_tag']) && !empty($_REQUEST['product_tag']))	{
			$optsetlect=$_REQUEST['product_tag'];
		} else {
			$optsetlect=0;
		}				
		$args = array(
			'show_option_all' => esc_html__( 'Все категории', 'woocommerce' ),
			'hierarchical' => 1,
			'depth' => 2,
			'class' => 'cat',
			'echo' => 1,
			'value_field' => 'slug',
			'selected' => $optsetlect
		);
		$args['taxonomy'] = 'product_tag';
		$args['name'] = 'product_tag';
		$args['class'] = 'cate-dropdown hidden-xs';
		
		wp_dropdown_categories($args);
		?>

		<input type="hidden" value="product" name="post_type">
	
	<?php endif; ?>

	<input type="submit" id="searchsubmit" value="" />
	<input type="hidden" name="post_type" value = "product">
	<input type="hidden" name="sp" value="1">
</form>
