Dynamic Sidebars

No... column control is best-managed by:

1. edits to tpl_main_page.php (where you can disable left/right columns for specific pages)...

// the following IF statement can be duplicated/modified as needed to set additional flags
  if (in_array($current_page_base,explode(",",'list_pages_to_skip_all_right_sideboxes_on_here,separated_by_commas,and_no_spaces')) ) {
    $flag_disable_right = true;
  } 

EG

// the following IF statement can be duplicated/modified as needed to set additional flags
  if  (in_array($current_page_base,explode(",",'shopping_cart'))  ) {
    $flag_disable_right = true;
  } 

There are comprehensive NOTES in tpl_main_page.php for column display customisation

Tried this one so far, and it works flawlessly! Thank you so much. I'll explore the other options too.

When you empty the cart, it carries over the missing sidebar, is there a way to put the sidebar back in in a situation like this?
