I was going to use the Multi-select feature, but when I got my actual content from the client, I recognized that it will not make sense for my website.
I have a large amount of categories, but they are all nested underneath only 4 parent categories. For some reason, when I was filtering with Multi-select boxes, with the Hierarchical option checked, I could exclude my many child IDs simply by excluding their parent ID—perfect. However, now that I’m trying to use the Dropdown input type, I actually can’t check the Hierarchical option or else excluding IDs doesn’t work. As a result, I have to exclude every single ID that I don’t want.
Is this a bug? If so, do you have a fix?
