I have a big data dump with a lot of brands I'm not really concerned about. Instead of going through Excel and removing all of the items that are assigned to these Brands, isn't there just a way to exclude them in Tableau? I don't mean filtering them out using a quick filter but make them so they aren't even visible in a filter to begin with.
One way to do this would be to create a parameter. However, this will only give the option to make one selection at a time, and if you have lots of members in the field, it could be a very manual process. I would recommend adding this to the Ideas section!
