Only if you know Opencart 1.5 framework!
The OC can show many products in a list and use function addToCart with quantity=1 if a product has no options.
If a product has options it redirects you to product/product and you must select options and quantity.
I want to extend the list and show all the products in a style of product/product.
Consider like the [url removed, login to view]
with input quantity and options(if any) for each item without redirect.
Consider that in [url removed, login to view] you click on a category on your left and the list of items on your right changes without the page redirection. Remember that the page contains only the list neither the description of category nor refine search.
I want a bid for each task separately, only if you can start it immediately after the award.
