show selected filter

Hi,

There is no such system with HikaShop. To be able to get that look, it will require some customization of the file "filter" of the view "product" via the menu Display>Views by a developer.

Hi,

well, the code in the "filter" view file, that you can edit via the menu Display>Views, will require a big overhaul.
You'll need to add the small images at the top, with custom javascript to hide/display the divs of each filter, and then, if you want to go further, you'll need to add further javascript to display a list of the number of results possible with an ajax request to submit the form and get the results in the javascript, count them, etc.
So it's a big task if you want exactly the same result. But it's possible.
