Sort by price etc

Hi there,

I hope someone can help me?

I’m looking for a plugin that adds some kind of menu in a sidebar/widget area where customers can sort shown items by price, category, name etc.

Like when you’re in a shop and can sort things by price.

I’m working on a deal site and need to make a list/menu where customer can sort by – to narrow down the results.

I’m unfortunately not allowed to show the site, so hopefully you can help me without viewing it.

I’m using WPGroupBuy.

Thanks in advance.
