Thanks @Tlahey. @Sabrinavigil @SimonLeclercq @MARIEDELATTRE do you think that's possible to do this on the summary of the Accordion component (Web)? Thanks in advance for your help.

Hi, from a design point of view the number of filters selected doesn't bring any value to the UX. It's better to show what is selected with chips for example (outside the accordion) like on the website. My reco is to validate with your designer if you implement chips I think it could be ok to don't have the badge in tehe accordion (which bring zero value).

Hello @MARIEDELATTRE, for more context, the feature come from a mock from UX designer Alexandre Nacache and we have done a meet with @Sabrinavigil.

Hi @Tlahey, after discussing with @Sabrinavigil, we will accept your request. It will cause a dephasing between the design & dev of Vitamin, but we don't want to hold you back and we've validated this behavior. Thank you.
