Hello
The plugin does not have this feature. You need CSS code customization. But how do I see you on the right way. Please describe the problem in more detail.
As you use premium version, write on support on envato( use contact form ) – https://codecanyon.net/item/woof-woocommerce-products-filter/11498469/support
In general, I need the same effect as on the page I gave (https://www.colorland.pl/fotokalendarz).
1) If I click “A4 Vertical” and then “A4 Horizontal” chooses two formats, but I would like to that the second exclude the first.
2) If I click “A4 Vertical” or “A4 Horizontal” I would like to be able to click on the category e.g. “All” or “children” and the format is not excluded from the category but the category with the category already
3) I would like to apply glyphicon instead of images
Hello
I already answered you to your email. At this stage there is no evidence that you are using a license. I can not support third-party products
For all that you wrote you need a customization code
