You can find this code in Section->collection-template.liquid file. where from you can find and change/remove.
Hi Jasoliya, thanks for your message. I found the code. Only I'm not sure where to change it. My filter is color and brand. The tags are brand_XYXYX or color_XYXYXYX. If I now click on the filter Marke then only the names of the Marke should be displayed XYXYX without Marke_.
As it should be displayed as an example when I click on marke or color:
Adidas Arkistar Armani Exchange Asics (So without the word "Marke“)
Schwarz Weiß Blau (So without the word "Farbe“)
Marke is in German „Brand“
Farbe – Color
Then you have to split tag from "_" and then show it. but for that you need liquid code knowledge without it you cant do.
