I am a beginner level user, creating my first web app for my organization. I have been attempting to set up a filter with a drop down menu so the user can select from a list of counties. I keep getting an error: "Please set up filters correctly". I don't know what I'm not setting correctly. I figured out how to make an individual filter for each county, but this looks cumbersome. I just want a drop down box...is this possible, and if so, is there a 'how to' document for doing this because obviously I haven't been able to figure it out and the YouTube videos are really slim pickings on this topic. Any help appreciated! Thanks!
