Woocommerc – left sidebar problem

Hello,

I am having some problem with this theme regarding left sidebar when using Woocommerce.

At first my left sidebar was always on the bottom, then i modified function.php with this code:

remove_action( 'woocommerce_before_main_content', 'woocommerce_output_content_wrapper', 10);
remove_action( 'woocommerce_after_main_content', 'woocommerce_output_content_wrapper_end', 10);

add_action('woocommerce_before_main_content', 'my_theme_wrapper_start', 10);
add_action('woocommerce_after_main_content', 'my_theme_wrapper_end', 10);

function my_theme_wrapper_start() {
  echo '<div id="primary">';
}

function my_theme_wrapper_end() {
  echo '</div>';
}

and now on some products left sidebar is on the left and on some products it is still at the bottom. From my point of view problem is with main product “primary” width. If title of product is long it will push sidebar to the bottom. Or if there are more than 3 products in category.

For example:

sidebar at left

sidebar at bottom

I would appreciate help with this problem, thank you.
