|Well, technically, what you're seeing is a list. It's actually an active list. As you add and remove things from the column they should appear and disappear respectively from the filter list.|
All you need to do is make sure there's a check next to the items you want to appear in your spreadsheet. For quick use, there's a 'Select All' button that if you check the box it will either select all or unselect all. Hope this helps.
