Order by dropdown functionality in category pages

-- url of the page with the problem -- : adellin.gr/index.php/%CE%BC%CF%80%CE%B1%...AD%CF%84%CE%B5%CF%82

Hi,
i would like to add an "Order by" select input at the top of the category pages.
How is this possible?

Kindest regards
Alex

Hi Alex,
The solution will probably be to use filters to do that.
Note that Filters are only available in the Business edition of HikaShop.
