the filter webpart is too weak in sharepoint online. I am looking for a customized filter webpart for sharepoint online. I tried to find the vendors but they all can only run on server, not sharepoint online. Do you know any vendors can provide advanced filter webpart for sharepoint online?
something like this. it has demo on it. you can try it out. I am looking for company that can help me to create such webpart on sharepoint online.
