I'm building a shop for my own web site and am currently
working on the shopping cart, specifically the page to
view and edit the cart contents. I'm considering combining
the quantity text input box and 'remove' buttons with a
pull-down list.

Shopping sites usually let visitors remove items from their
cart or change quantities. Typical controls include a 'remove'
button on each line, a text input box of the quantity ordered,
an 'update cart' button and, sometimes, an 'empty cart' button.

I'd like to replace the text box and 'remove' button for each
line in the cart with a pull-down (select) quantity list. The
list would contain all numbers between 0 and the number they
ordered for each item. The selected number would be the
order quantity. The things in my shop are typically available
in quantities of 1-10 per item; the quantity box could
contain numbers up to the quantities available.

For example, a visitor puts 3 of something in their cart but
2 more are available. The pull-down list would contain:

3 <- selected

To remove a line from the cart, the visitor would select 0
(or 'none') from the list. To change the quantity, they'd
select the required quantity from the list. They then select
'update cart' to make all the changes. I'd also have an
'empty cart' button.

Pros: 1) less form elements, 2) no need to move between mouse
and keyboard to edit quantities

Cons: 1) I'm not sure visitors will guess that there's a
zero quantity in the list (a small note on the page
could address this)

I'd be interesting to know whether anyone has seen anything
like this on sites and whether people think it's a good or
bad idea.
