There are any number of ways, but you need to know which items are not
to be shown. One way would be to set a "hidden" modifier with a "hidden"
field in the database, then load it automatically into the cart with
this in catalog.cfg:

    AutoModifier  hidden

Now you can do:

[item-list]
   [if-item-modifier hidden]
   [else]
	Show the item: [item-code]
   [/else]
   [/if]
[/item-list]

Also, remember that the cart is nothing but an array of hash
references. You can program almost anything with embedded Perl.

[perl]
	my $cart = $Carts->{main};
	my $wanted = $Session->{arg};

	for(@$cart) {
	    $cart->{hidden} = 1 unless $cart->{code} eq $wanted;
	}

	for(@$cart) {
	    next if $cart->{hidden};
	    $out .= <<EOF;
Here is the item, $cart->{code}. You have $cart->{quantity} in your basket.<BR>
EOF
	}

	return $out;
[/perl]
