I just tried to add a new "feature selection" input variable to my Hikvision camera driver but the check boxes don't show on the device home page. I get the list but its not check boxes. Here's how I have it defined,

input name: "Features", type: "enum", title: "Select Camera Features",
required: true, multiple: true,
options: ["AlarmIO","Intrusion","LineCrossing","Motion","PIR Sensor"]

If I create a new device, same thing. I sorta can't believe it's not working... what am I missing???

I know this works in apps, but I'm honestly not sure it ever did in drivers...
