Brand filter

[grapek]

Welcome

 

I have a filtering problem

 

So my products are filtered in 4 ways (Color, Size, Category and Brand)

 

The first three forms of filtering work properly. ie After selecting eg one of the available colors, I show the corresponding products and in the filtering options I have the possibility to select the next colors for filtration. Thanks to that, I have the ability to filter, for example, 4 colors at a time. Same with size and color.

 

The problem is with the brand only. I have 3 of them and unfortunately I can not filter products for example by selecting 2 brands.

After selecting a brand, other brands disappear and I have the ability to filter only 1 brand.

 

I would like the brand filter to behave identically to other filtering options. That means I can filter 1 or 2 or 3 brands at once and not just 1.

 

Please help

Thank you for your answer

 

And do you have an idea how to do so that you can filter after several brands at once?
